I'm having a temporary retail warehouse sale Nov and Dec in a suburban area in a smaller mall that is on the decline. 24,000 sq feet in an area that is ok, but some sketchy characters in the area. Any ideas on security? We mostly take payment in credit cards and some checks, not a ton of cash but thinking it might be looked at as lots of easy cash for a couple of bad guys. we close at 5 so will be locking the door soon after that. I will talk to the local police and get their scoop on the area and hopefully they'll try and make a swing by around closing time. There are dock doors that will be locked so only one main front door. I'll be carrying of course. Any other ideas on some security precautions?
