Thanks lads, I didnt rank up at zone 18, i waited till i was fourth in q then went up to it and realised it only takes cards and i hadnt got mine with me, just saw on the machine it said 3 euro min but i understand now if you are only there for 30 mins it charges you 1.50, i might try it again tomorrow, on another note i pulled into macs carpark and was asked to move as well, funny thing is when i pulled in there was allready people sitting in their cars, and yet that guy was only asking the taxis to move, he didnt ask one private car to move.
