Hahahaha
Plus One. That's a corker.
I suppose this anecdote is an example of unprofessionalism when I was a waitress in a big restaurant ten years ago.
I was looking after a huge table of Americans who had been very fussy throughout and I was rushed off my feet by them.
At the end I gave them the bill and the service was added. One of the Americans said he didn't think they should pay it as since they had been on holiday they had had service or VAT slapped on to everything. (He had no complaint about the service btw).
I could hear all this as I cleared up around him and so I said,
'Excuse me, are you criticising this country's tax system? Only I have a brother fighting in Iraq along with Americans right now, willing to give his life for your president and you come here and don't want to pay the service'.
I squeezed a couple of tears out and walked away hurriedly as if I was overcome with emotion.
They looked mortified and paid way more than the suggested service at the desk sending good wishes to my imaginary brother, while I was out back shaking with laughter.
My boss also thought it was hilarious but said I shouldn't make a habit of it.
