I worked in Our Price records when I was 17, one Sunday we were getting ready to shut up for 5pm. Some guy had been stood at the counter listening to CDs on headphones for an hour and when we said we'd have to turn the stereo off and shut up shop, he got irate, he vaulted the counter, threatened us with a screwdriver and demanded we put another CD on for him to listen to, brandishing the screwdriver at each of us. Someone discreetly called the shopping centre security and they and the police carted him off.
A few years ago I witnessed disgusting behaviour. I was waiting at the bar of the Radio 2 festival in a day. They had this thing where you paid £2 for your hard plastic souvenir glass for each drink, to save on wastage, great! At the end, you could return the glasses for full refund, or keep them a memento.
Anyway, some big bloke stood next to me at the bar orders six pints (which were overpriced like this sort of events usually are, but you expect that) the young girl serving him was about 18, tiny, lovely, shy girl.
When she told the bloke next to me the price, it was £12 more than he expected (he'd not read the multiple signs about the deposit scheme littered throughout the huge queue) and took umbrage to the £12. The girl politely tried to explain what the £12 was for, but he wouldn't let her finish. Was literally screaming in her face, ranting about the £12. All the bar staff were equally young and looked petrified, not one colleague, or customer stepped in. Security were too absorbed in queue control.
So, I tapped him on the arm, smiling to try and placate him, and said, "C'mon mate. Give the girl a break, she doesn't make the rules. You can get your £12 back at the end... "
He turned to me, loomed over me and said, "What the fuck had it got to do with you, you fucking nosey bitch? Keep your fucking nose out of it!"
The girl started stammering and said to me, "It's okay, don't worry... " she looked so scared, I'm ashamed to say that I actually lost it and yelled at the bullying twat, "Yes it is my fucking business, this young girl does not get paid enough to be spoken to and treated like this, so why don't you pay for drinks and just fuck off, you nasty fucking cunt!"
He muttered some sexist insult at me, slammed his money down and walked off with the carrier of drinks. The girl was shaking like a leaf.
The adrenaline kicked in and I started shaking too. I'm short and he was huge, but he made me see red. I got my drinks and as I left, he was waiting for me near the exit with his wife / GF and was telling, "There's the mouthy cunt, she better watch her fucking back the rest of today!" she was smirking, she didn't look scared, but proud. I couldn't believe it, I gave her a look of pity and told him to fuck off and pick on someone his own size and walked off as fast and confidently as my shaking kegs would allow.
