Why would a McDonald's have security people looking for cameras?

Never been to France. Been to several McDonald's with security guards. I'm pretty sure they had CCTV. Not a front for money laundering - it was that kind of a neighborhood. Eastern Market has gentrified a bit since then ...

Anyway. A no-camera policy could be put in place to deter snoops. Guys working for the other team (Burger King). Maybe they had a bad experience with guys taking pictures of other patrons.

Ah - you're just trolling, aren't you?
