Never Been Treated Like This...

I park in the very back where us says customer parking only to do some shopping. Plenty of room for my Class C with Jeep Wrangler in tow. Security guard drives up and mumbles you can't park here. I say how about if I'm shopping? Mumbles again about how it's employee parking and I point out it doesn't say that. It was mid day for Christ sake, not like I was trying to hunker down for the night. I just wanted to park where I was out if the way.
