Had a really bad day today, its unbelivable all whats happened today i almost find it amusing, ive lost a bit of faith in humanity today.Yesterday i went to a party and i had an argument on the tube with my friend on the way there he told me not to act stupid at the party as he was trying to get clients for his work he had already told me this earlier and i got offended and told him not to tell me how to behave and he was telling me to lower my voice i told him how would u like it if i told u how to act he kept telling me to lower my voice and i called him a prick he had  a big grin on his face so i told him to fuck of and got off the train at the next stop he came running after me and told me where am i going i told him im not going to be treated like that he appologised and said i was right and he shouldnt have spoke to me like that and at the party later he appologised again so hopefully he ll respect me alot better in the future otherwise no matter how much i get on with him he wont be my friend anymore, but the party was really good and we left at 4.I started work at 9:30 today and it was a nightmare!!! 2 boys came in the shop whist i was on till and the security guard from the arcade next door came in and told me to keep an eye on them, i got eye contact with one of them and he shouted at me "who are u f_ing lookin at" security then removed them and i said to him which i know was wrong but i couldnt help it as he was small "who do u think u are napoleon" he just carried on swearing but was lead out by the security guard, about 20 mins later the boys came back when i was on my own and were right up in my face, i cant help it but in situations like this i start shakin as i hate intense things like that so they could tell i was nervous which makes it 10 times worse i just kept tellin them to leave the shop and told them couldnt they see theres loads of families around, he repied he doesnt care about them then i thought id try and befriend him which worked thank god i walked up right in his face and said i admire your bravery and his friend said to leave it and then they left, i was servin customers at the same time as this was going on on till so this was a really difficult situation and i was shaking for a good 5 minutes after they left i hate the way i shake i see it as really unmanly and would do anything to be able to stop that from happening. A bit later on a customer had her purse stolen in the shop and i had to help her look for it even though i know it would have been taken she told me to call the police i said i would and asked her if she needed to cancel cards, she said she didnt as they were kept in a different purse she. then she left i didnt call the police because that situation has happened so many times and theres nothing the police can do as we dont have cctv.Situation 3, customer starts arguing with one of the staff i told the staff member to calm down and she kept on arguing with this guy then she just walked off till and shouted at the customer u dont know what shouting is!, the customer then instead of telling me whats the problem with her said to me cant u control ur staff, i dont think u can be a manager as u let her behave like that, i told him that im going to sort her out but id deal with him first can u please tell me what she has done to upset u, he told me she had been rude to him and accused him of pushin in, i appologised to once again have him give me a torrent of abuse about why im not fit to manage people i said is that anyway to talk to someone who is giving u there full attention and how could i deal with her at the same time as she had left the shopfloor unless he expected me to shout after her in the same way she had shouted, I then had to go and find the girl i was plannin on suspending her as i felt humiliated but i thought id talk to her and warn her if that ever happens again that she will be suspended, so when i got her in the office i said ur bang out of order and she is a very agumentative girl but she admited that she was wrong and that it wont happen again, i said it better not, she appologised to me later on.And coming home today i saw about 10 teenagers jump one boy for his phone and give him a bit of a beating, i really hate seein things like that and think ppl like that are the scum of the world and cowards!! i hope what comes around goes around for them!I think all the situations today i handled well and i tryed to sort them out to the best of my ability. i just need some advice on how to stop the shaking as it gives away my true feelings and doesnt make me look strong no matter how hard i pretend!hope everyones okay< gonna get loads of sleep today for what i know will be a better day tommorrow, if anything i have more respect for myself now!
