Live mas, but let the cops in when they come knocking, Boston officials tell Taco Bell

How do you check for overcrowding at a closed restaurant at midnight?

All of the things you list could be completed during normal business hours with the side perk of having management present. Better yet you will not have to wait in the rain for 5 minutes... those poor things.
