When I was 17 I had just left school and was working full time in various cafe/restaurants.
In the cafe a woman ordered a sultana scone. We had sultana scones and plain ones. She stormed up to the front where I was serving, and shouted at me saying I had given her a plain scone instead of a sultana.
I tried to apologise and say I'm sorry, it is a sultana one I gave you but here is another one (so she could directly see I was taking from the cake stand marked 'Sultana scones').
She wasn't having it and stood there giving me a barrel load of abuse and shouted ''you need to get back to school hen''.
By this point a queue had formed behind her and I was nearly in tears she was so nasty to me. The other customers just looked down awkwardly while the other staff members just stood and watched rather than trying to step in.
I've never known someone to be so nasty over such a tiny issue. There's no need for it at all.
Another time in the restaurant I worked in, a man and 2 women came in. They requested I seat them in the conservatory, I replied sorry but they're all booked up. He then argued with me saying there was no one sitting there so why couldn't they sit there. I again tried to explain that we leave a 1.5 hour between bookings so people were due to come in well before he would be finished eating.
He then demanded to see the manager and said he was going to report me for this.
I got the manager to go over who echoed what I had said.
The man then did not speak to me for the entire time he was there, even the women ordered his food for him, he didn't say please or thank you, and when I would go to check if their meals were okay he just stared at his plate and didn't say a word.
Awful, bitter, horrible people. I think the fact that I was clearly a young girl made it worse in a way, almost like they felt entitled to talk to me like that.
I'd never work in hospitality again, I'm now halfway through a degree so a big middle finger to the woman who told me to 'get back to school'! I'm 20 now.
I always try to be extra nice to retail/hospitality workers, need to try and make up for the shitty customers.
