I played 2 sessions in a day.
morning session I had $7500 coin in. saw $15 comps immediately in my acct.
evening session I put in $100 in $0.50 JoB before going to the comedy club.
lost that $100 pretty quickly. 
I didn’t check my acct while I was there.
I came home the next day and checked my acct online.
It still says $15 comps?
so it’s not earn at least $5 comps per day, else you get $0, it’s earn $5 comps per session?
that means pulling your card out to check your balance in another machine resets it back to $0 and you start all over again.
