strange compulsions?

when walking home from the north side, i pass a number of restaurants all with outside seating. - heartland brewery, republic...etc..pedestrians walk right next to all the restaurant customers eating their various plates of food and i've always contemplated how easy it would be to reach a hand out and snatch a glass of soda or a plate of clear glass noodles or a salad. or to take the fork and just steal one bite before moving on. not that i have.
