Keep The Seats Clean

There are certain signs that don’t need any explanation and there are others with written information that takes up our mind to understand what the sign is trying to convey.  Just like this one, what anyone can make out from the sign on the board is “don’t put your feet on the chairs”. These signs, in general, are difficult to understand. For example one of these signs prohibits from sawing the chair while the other prohibits musical instruments to be played and many more. Hopefully, someday people will understand what the creator wanted to say.
