Shitty Work Experience

I still remember having to go to work in a Starbucks milkshake cafe for work experience and it was atrocious. The feeling Of just waiting for an order or having to deal with customer orders was trash so I just sat in the chair most of work when it was boring and my boss shouted "what is he doing here" to ally he workers and one employee came up to me and said if our not working just pretend to work but tbh I didn't listen and walked around he work place lol. So then after Wednesday I left the room where I got my jacket and bag and when I shut the door some big position in the work force just shouted to all the employees "why is this guy working here" after I was walking home I didn't think nothing of it. Until my parents got called by the school and they said the place didn't want me there anymore and I had to go to the library to do nothing for 2 days. When I was in the library I overheard a teacher's conversation about how I looked like I didn't want to be there and I didn't do nothing in work experience and was confused. This crazy ass teacher that was in charge of the office one day approved me in the playground when I was doing laps cause I had nobody to talk to and just said do you want to do a C4 or I will drive you to the workplace and force you to apologise to all the staff in the workplace about your behaviour. Then she gone on a rant about how trash my behaviour was in school and how I caused the most behaviour problems but I needed up with nothing in the end. Sorry for my shitty language I'm pretty dumb and had no GCSES
