I pay my cleaner £11.00 per hour. I didn't get round buying a present as rushed off my feet right now. She is my first cleaner and has cleaned 3 or 4 time for us so far.
Would £ 10.00 be stingy ( I only have a tenner at home and can't go out before she comes)? We live in London if that makes any difference.
Would it be ok to pop a ten pound note in the envelope with the Christmas card? Sorry, whats the etiquette here please?
