I had lunch at Hungry Jack's today, just to observe a curious phenomenon I have seen there before.

The toilets there have large red signs on the doors, readable from across the room, saying "Please ask our friendly staff for access to washrooms" - that is to say, the toilets are locked and only staff members have keys. I find it fascinating that people continually go up to those doors and push on them. Some of them even obviously read the sign before pushing on the door. What do they expect to happen? It has puzzled me for about four years. Do people think the signs don't apply to them? Surely these doors know I'm not going in there to shoot up, so they'll open for me!
