What's the most public place you've had sex

In a walk in closet, no big deal right? Except it was a mock up closet in the bedroom section of Ikea. What we didn't know at the time is that apparently Ikea has hidden short cuts for staff so they don't have to walk miles to get 10 yards and this fake walk in closet was one of them, in the moment we didn't see that this "closet" had 2 doors, we got caught in the act by an Ikea staff woman who was maybe on her way to lunch break, and politely asked to leave the store immediately, so we walked the endless trail that is Ikea to the exit while being loosely followed at a distance by security - no meatballs that day.
