I work in a coffee shop. Today has been one of those days 
All was going well until a customer slammed his drink down on the counter in a fit of rage, all because we were doing takeout cups only. (Dishwasher broken) and the engineer is due this afternoon. You can still sit in but can only have takeout cups. Head offices decision, not ours.
Said drink went all over myself and his hands. It was a large black tea so you can imagine how hot it was.
So now I've been sent home and I'm pretty bored. Does anyone else have and interesting customer stories? Do tell I need a rant
Oh and one last thing. We had signs all over the shop and shop front stating we are doing takeout cups only.
