Sometimes I do salon bingo! I drawn out a card of squares, say 3 by 3 and I put a task, treatment or retail product in each square. If the therapist gets a line, she gets a small reward and if she gets a full house then she gets the star prize!
It's up to you what the prizes are and if you run the bingo over a week, weekend or just a day. We have great fun with it and the first week I brought it in, the salon profit nearly doubled!
