We went for a crafty ruby at Paprika last night after working late.
I don't check restaurant bills to the last decimal point, but I do generally run an eye down the list of things for which I'm being charged.
"What's this?" I demanded last night when I didn't recognise an charge.
"It's the 20% discount for early and midweek dining," replied the waiter.
I looked again and the rogue item did in fact reduce the bill. I decided not to insist on its removal and tipped more heavily than usual to hide my embarrassment.
