This was actually at a grocery store not a restaurant, but it was so absurd I'm posting it anyway. The guy in front of me at the checkout was buying a few items, including a pineapple, which is sold be weight. Right before his turn to check out, he ripped the crown off the pineapple (the leafy part on top) and shoved it in over by the gum and mints rack. As a portion of the weight of the pineapple, that must be nothing, saving him what, a penny? The cashier actually did scold him and he just kind of grunted in acknowledgement. Figure if you do something like, especially so shamelessly in front of others and just shoving the crown in with the gum, that you're kind of a sad enough person to feel sorry for.
