Why do people tip the attendants who pay out hand jackpots on slot machines? These people do absolutely nothing except pay you the money. They had no role in you winning or pointing you in the direction of what they believe is a "hot machine"(that is, even if those exist)They really don't even need to be there. Why do you need a hand payout these days when all the machines dispense a ticket that you can redeem at the cashier or a kiosk?
