Has any one ever gone to one of these? The biggest problem is safety. You must be on site - no credit cards - no check - and cash must be on hand. Anyone at anytime could pull out a gun, take everyone’s cash, put everyone in a unit, close and lock the unit, and walk away with a hefty amount of cash. It may take a few hours or a few days before anyone ever noticed that the people were gone and someone finds them. Before you go to an event like this make sure that you know the area and the business. Do they have security cams in place? Do they get a copy of ID's or do they just let everyone walk in? If you go be safe.
