Interesting situation at the petrol station, where for some reason they made the guy in front of me pay for my petrol, which caused them to panic slightly when I tried to pay for mine. "But the guy in front of you already paid for that one". Apparenly:"Cool, have a nice weekend" wasn't the proper answer. After waiting for 10 minutes while petrol-station lady was arguing with the Polish guy that was about to leave. Then for some reason she couldn't get the cash-register to accept my company-card to pay for my own petrol. Ended up getting billed for 35 euro's worth of oil instead. Typical.
