Supermarket Cluedo

Did you notice how people passing by you in a Supermarket would look through your shopping cart?And not only look but sometimes stare? And the funny bit is that after checking out your cart people would always look at you. It's like playing Cluedo, first they see the items in your cart (the clues) and now they are looking at the suspect. One time I decide to mess with people a bit so I filled my cart with pickle jars (like 15 of them) and on top of those I put 2 packs of 8-roll toilet paper and man did I get some seriously confused faces :D
