Many years ago, I worked at a big 21 screen theater in Boston for a while...
Would find wallets and purses all the time, sweeping up between shows.
When I took them to lost-n-found, apparently I impressed the manager because I left the money in them.
He gave me a quick promotion to the moneyroom... counting all the money exchanged (the bank deposit) at the end of business hours.
Good memories, Good times
