Because they want your money, bad. I wonder what kind of machine is sophisticated enough to accept four different denominations in any orientation but can't give change. I think if a machine can potentially shortchange you by more than $1 it should be required to give change.
Maybe because despite the fact that soft drinks cost < 50 cents a can to produce (for cola anyway), lottery tickets have even less value?
And I suppose there's always the chance that they might be able to prove that a jackpot winner stole a ticket if a particular machine got a lot of bum-bills at a certain time.
omg at our store we sell so many. it's staggering. BUT--man oh man, we also sell so many cans o pop. i dunno. people love a soda with their scratchers?
