Spain is a very popular tourist destination for Europeans, and any tourist worth his/her salt knows how to ask for the bill at a restaurant:
La cuenta, por favor.
However, a couple of months ago, a Dutch radio DJ, who often goes on holiday to Spain, said that you can also ask for la multa (the fine). You would certainly be understood and the waiter would appreciate the wordplay/joke. In my native language (Dutch), it wouldn't work, but we do have an expression for this occasion which literally translates to 'How much is the damage?'.
My question: is this really true, or did he just make it up? I couldn't find any references to this usage in online dictionaries, e.g. Spanish Central.
