Donating blood, when did that get expensive?

I'm on holiday right now from work. That means I'm just sitting at home doing all the things I usually don't have time for since I can't be bothered to go anywhere. So today my schedule (not as bad as it sounds!) said "donate blood!". So I filled in the "free parking" note that we blood donors get, took the car up there and got tapped for a pint. Then I got back to the car and ... yeap, got a parking ticket! Why? Because I hadn't put the not up against the windshield! It was in the passenger seat so whoever that parking attendant was should have seen it, but nope. THat cost me 300 SEK :(
