OK, to the person who tore wallpaper in order to get to a power outlet, I really hope I never meet you, as I have absolutely no respect for you now. Do not destroy/deface someone else's property like that. And for the café, I know it's not a perfect solution, but beyond solutions like obtrusive locking outlet covers, or turning off outlets at the breaker, you could also look at swapping the outlet out with an L5-15R. That's the same voltage & amperage as a regular 5-15 receptacle, but uses a circular plug that pushes in and turns. You'll see them (or a similar amperage) on certain Metrolink (in LA) and Caltrain Bombardier cars. You could either get an adapter (NEMA L5-15P to 5-15R), or change out the plugs on the stuff you'd plug in (like vacuum cleaners). And no, it won't stop someone who is absolutely determined, and who is willing to go out and buy an adapter. But it makes it all the more obvious that this receptacle is not for people to use.
