Can you sleep while sitting anywhere in public places?

I always see people who are sleeping or closing their eyes while in the public place waiting for their turn. Like in the bank, or in other public offices where you have to wait for your number to be called? It is very boring waiting for a long time. I myself do not like a long wait. I often go out and just come back when my turn is almost there. What is funny is most people who are sitting there waiting are sleeping. did you experience that. I really see them and sometimes I am tempted to do it too,
