Be wary of paid parking lots

Sometime when you have some free time, do a check against a watch when you get one of those parking tickets in garages. Then check again when you’re leaving and pay at the attendant. Many times, the parking lots purposely off-sync the entry clock and exit clock. This way if you manage to cut it close to an hour, then they can charge you for the next time period up.
It might not happen at some garages, but from what I’m told, it seems to happen at a few of them. Very sneaky, and definitely unethical.
