Point cards are everywhere here as I'm sure they are in North America. Most are just functional and not much to look at but I went to a nearby "kaiten" (conveyor belt) sushi place the other day and as I was paying I saw these point cards.
They are for kids only and they get a stamp for each time they come in and after 10 times they get a gift. Not sure what the gift is but I'm sure the kids would be happy! I asked the lady at the at the register if I could take one and she looked at me like I was crazy so my hubby said that it is so cute that I would like to keep one. I'm sure that gave her something to talk about!
