LOL, maybe it's just a different version of passing the collection plate in church , AKA " the Sunday morning stick-up " so not sure if it's the collector who is the mentally ill one, or the fools who give them any money ..
At least in church folks hope that some of that money goes to a good cause ( what's left of it after the priest lines his pockets with it, that is.. ) whereas I'm going on a limb here and presume that not a penny of tne donations collected by the orange street monks ends up helping the needy ...just the greedy .
