There is a bus stop near the Circle K with “NO LOITERING” stamped in numerous places around the bus stop.
How do you know if somebody is waiting for the bus or loitering?
If a guy is drinking from a can of beer in a paper bag, and he is already wasted, it’s quite likely the guy is loitering.
Marty, the local dog walker had another method, one easier to measure. If the guy is at the bus stop, the bus stops and goes, and the guy remains at the bus stop, the guy is loitering.
