A gun shop about 5 miles from me, where I'd been doing business for years, changed owners about six years ago. A very young guy -- early 20s -- bought it, and his father works there part-time helping him out. Dad is, shall we say, a little rough around the edges.
About 18 months ago, I had an out-of-state purchase shipped there for transfer. I got the notification that it arrived late on a Tuesday morning and called the shop around noon. Dad answered the phone, told me that yeah, UPS had made some deliveries to them, but he hadn't unpacked them, and he would call me when he did.
My route to and from work takes me past that shop, and I stopped by there on my way home around 5 PM the next day...about 30 hours after the gun had arrived at the shop. When I walked in the door, Dad looked at me, and in front of about 8 customers, yelled out sharply "Didn't I tell you I would call you when I got it unpacked???"
I left and drove home, and about 20 minutes later, Dad called me and very quietly told me that I could come in any time to do the paperwork on the gun. (We have a mandatory 7-day waiting period here.) I went in the next day on my way home, and the day I picked the gun up was the last time I've been in there.
I started using another LGS for my transfers. The new guy asked where I'd been doing business, and when I told him, he immediately guessed that it was the owner's father who'd caused me to take my business elsewhere. Evidently, I wasn't his only new customer...
