The are robbing bar-stewards for not giving change...I've been caught out a couple of times lately with that too. Also, donut is confusing as some is short stay, some long stay, you have to know which you are in and your bay number.......none of which you are aware of until you've got out of the car, ran to the signs and stood reading it in the pouring rain with kids screaming, before having to run back again to check where you are.
