Not lazy I don't think you'd dig ditches for $5 an hour in your spare time, just like I won't pick up pennies in my spare time
I see coins laying in the streets in the city of New York all the time and I leave them be. So do the homeless and beggars. Somethings are too filthy to bother with. Bend over to pick it up any might get hit by a cab. Saw a dime laying on the edge of the subway platform last week, too close to bother with, as it was laying in the yellow security stripe.
