In the UK we have something called Chip and Pin on our Credit Cards, basically you pop your card in a card reader and type in a four digit number instead of signing for it.. But what i notice a lot of people do is shield the keypad and bend over, (sometimes i have to double check im not wearing a black and white striped t-shirt), then as theyre typing it, they say it out loud as well.. its really baffles me, but its funny to tell them that they read it out because they get embarrassed and its the perfect payback
Trivial and not much of a rant i know, but when you (used to) spend all day on a till, even a pen dropping becomes a highlight of the day...
