Anybody tell me which car hire company doesn't reserve a rediculous amount of money on your charge/credit card ? Info about the size of the deposit was conveniently left off of the booking details last time around which led to one of those embarrasing moments.
You need two things in life - WD40 & duct tape. If it moves and it shouldn't, use the duct tape. If it should and it don't, use the WD40.
