What moment made you crash out and why?

I work in a 5 star hotel and i have to be EXTRA fancy for guests but i recently crashed out at a guest who said they ordered 2 orange drinks and i said ok so that's 2 orange drinks? And he paused for like 10 seconds looking confused and said no i said 2 orange drinks and i said ok so that's 2 orange drinks right? And he did the same thing AGAIN. I tried to hold my shit in but after the 4th time i lost it and i said " I'll shove my foot so far up your ass that your head will get screwed on right you MF" you can imagine the rest.... .
