I just stay away from that type of car park. Just because you've got in the door doesn't mean the won't be somewhere inside that catches you. I spose living in a rural area and having a natural aversion to shopping helps though.
It's not just multi-storey carparks that can be a problem. Many boats have height restrictions too.
I chuckled at that pic Rhubarb
I did when I was taking it.
But the forty five minutes of mayhem before the boat left? Whilst seriously hung over, clearing Turkish immig/customs whilst arguing with ships captain and madly trying to save extra cm's - not so much.
