Prudence and her beloved had been to farewell drinks and were a teensy bit tired and emotional, and most definitely not up to cooking dinner.
At the restaurant - one just discovered - they found the orange printing on white menu card to be quite hard to read in the orange light of an orange room. And commented thus to the waitress.
"Oh, that's OK," said she, somewhat disingenuously "we're closed on Sunday."
Prudence is still trying to work out how that makes it OK. But it was funny.
