How does one entertain themselves while standing around in a men’s room, not for biological functions but rather electrical outlets, waiting for one’s cell phone to charge in order to be able to use the GPS to get home?

Answer: finding the single largest contiguous pattern of same-color blocks on the tile floor (diagonal blocks don’t count).

This was, of course, performed in a one-occupant, lock-the-door men’s room. I’m not weird.
