Sure, all of the above. Biggest was a few years ago. The big shopping mall near us had built 2 new parking garages on either side of an anchor store. I was leaving and had to take the elevator then walk up half a level to my car. I met a man who looked out of sorts/scared. I got in my car and as I drove down the ramps I saw him again looking even more frantic. I stopped and asked if he was looking for his car. He said yes and he couldn't find it. I asked "are you aware there is an identical garage on the other side of the store?" You could almost see the light bulb going off in his head. He was so relieved!
