This is a great idea!
@stux If it brings a smile to their face, then it's well worth the couple of dollars you spend.
I'm going to try and remember this.
@stux Pre-empting customary questioning on the topic a former colleague of mine caused fairly hysterical laughter by trying to get a supermarket cashier to sign up to HIS personal loyalty scheme. He had a clipboard and pen to enroll, and when faced with giggles said w mock seriousness "Wait, wait, there are great benefits, let me explain. All you have to do... " Nearby cashiers were in fits. Made their day I think. (He was clearly joking.)
He died recently, far too young, and funny to the end.
