Your sister's engagement dinner needs a table for eight on the one Saturday everybody can make. Three weeks ago you booked three places for that night and let each of them think it was the only one. All three came through. Each one takes ten euros a head off your card if you cancel inside seventy two hours, or if you simply do not turn up. Your sister picked the harbour place last night, an hour too late for you to drop the other two for free. This morning at the school gate you mentioned that you had two tables you would not be using. Nikos, who you stand next to at that gate every morning and whose son sleeps at your house most Fridays, has just asked to buy one of them.
