I have two bowls on my desk overflowing with coins, pennies, nichols, dimes quarters. All from my pockets. Lately I have started to reverse the flow of these coins putting handfuls back into my pockets when I go out to use as tips.
Sometimes I think that tips have to be paper money but don't 4 quarters actually equal a dollar bill. I have to remind myself that it is alright to give coins for tips.
