I use to work at a place when I was 15 where the projectionist was the usher as well and we would use electric leaf blowers to blow the trash all down to the bottom then use a push broom and collector pans to get the trash. Then I would walk the rows ..use to find money every where..our ticket box would give out the $1 coins for change instead of 1$ bills and I would find them all over the floor ..even found a $100 bill one time. Helped since min wage was $5.25 then.
