You park here, I block you

In Dubai tower offices and residents' apartments, you may not park freely. Parking lots are assigned to you. This sports Merc had parked at the lot that wasn't meant for it, so when the right person came back and found the lot taken, he/she duly blocked it. If I am not wrong, the driver of this Merc would have to pay a fine.

This has happened to me before, but not being a seasonded Dubain, I have gone to park elsewhere temporarily.
