Glass-drop man

There is a litany of conspiracy theories and monster quests in the world: Bigfoot, Slender Man, Aliens.... I propose to you now that there is a man who drives around France and walks into restaurants to throw one glass on the ground. 

I developed this theory because I cannot go to any city for more than 24 hours without hearing a glass fall and break. It adds a kind of trademark to French restaurants, and has become a running joke between Anna and I. I do not know whether it's only one man or an entire glass slinging syndicate, but he/they are everywhere.

From now on, know that if you walk past a French restaurant and you hear the shattering of a glass, that the Glass Breaking culprit is hard at work.
