Originally the Swankers
Nevertheless there should still be a 20min grace period. The OP says they were there around 10 minutes. You dont have to give an excuse as to why you were there in the first place. You are perfectly entitled to drop passengers off. I do it at Shoreham most weeks. The OP could have been looking specifically for a space that suited their needs (whatever they may be) but decided somewhere else offered better choices. If they didnt overstay the 20 minutes they shouldnt have got a ticket. It should be thrown out.
Where are you getting the info that everyone gets free 20 minutes parking?
