Seoul signs

One of the things that I really like about traveling to new cities are seeing all of the signs.  Every country and even different parts of the US have different ways of communicating things on signs. 

This first one was actually on the back of public bathroom stall doors.  I assume that it is saying something about not spreading germs.

This is a map of a shopping area.  I thought it was a unique and artsy way to show the stores instead of the standard map.

This was on the outside of the subway.  I'd like to think that the lady is screaming "damn it" since she was so stupid to get her purse stuck in the doors in the first place.

This last one obviously isn't a sign but had to post it for the firefighters I know.
