I used to work in a restaurant, 20-odd years ago.
The manager was an utter bitch, and so were a few customers, always calling staff into the office for bollockings, even for just the most smallest insignificant things.
I went in one day with one hell of a migraine, spaced out, dizzy, etc., but I carried on working. I was pale and shaking, and while on duty, dealing with customers, I dashed to the loo thinking I was going to be sick.
One of the customers, a woman, could see I was really busy doing a trillion things, and I told her I had a migraine, so I'm not ''fully with it''.
She tried to crack one of her brain-numbing, boring jokes, which she always came out with, and thought she was exceedingly funny. I didn't laugh, just carried on working, and walked away.
Minutes later, the manager bitch drags me into the office. Apparently, the old fat cow actually reported me for not laughing at her stupid jokes, and she'd seen me running to the loo while I was dealing with customers and was busy!
I snapped at her that I was VERY busy, ill with a migraine and working my arse off, and would she rather I run to the loo for sickness or puke all over the floor? Then I grabbed my bag and walked out, never to return.
