But when I put in my coupon worth a few dollars, it wouldn't function, nor would it give me a cretit coupon back. So I cashed out-got a coupon and moved to the next machine where the woman just left grumbeling something about the machine. The first machine took my $20, I lost a little then won a little on the first 25 cent machine. I stopped by to have dinner and drop $100 in the slots.
