....It just really bugs me. To the point of utter revulsion.
In a supermarket, grown adults opening a pack of 4 pork pies and happily munching their way around the shop, only to toss the empty pack to be scanned as their shopping goes through. Why do people do that, have you ever, and why??? (DD had to wait until the car for her gingerbreadman biscuit from Waitrose).
