The workers at this Dunkin’ Donuts hope that you’ll be happy enough with their service that you’ll leave a tip. But doesn’t trust you not to run off with the tip jar.

Consumerist reader Chris snapped this photo of the bottomless tip cup at his local Dunkin’. You can see in the picture that there is a hole in the cup and this hole continues through the counter and, presumably, down to a larger tip jar below.

Do you think this encourages or discourages tips?
