I was hoping to forget this one, but...
Music-Go-Round (used gear store) near Raleigh - I've been in that store 6 or 7 times in the past and bought 2 basses, many pedals, drum stuff, etc. there.
I was looking to get my son a bass for his b'day and this place had a new Schecter Diamond Series as well as a few interesting basses. I've got $800 in cash on me. I'm dressed like I'm always dressed - athletic shorts, sneakers and t-shirt. I go in there, I see one of the clerks in there who used to work at another music store. We talk for several minutes, and he gives me a cord and tells me to knock myself out. This may sound odd, but I usually have a guitar cleaning cloth with me when I visit stores. I give 'em a quick rubdown before I put em back.
I swear, I'm just checking out instruments - checking the neck, electronics, sound, feel, etc. at like 1-2 on some crummy amp so only I can hear just how terrible I am - I try 2 basses - less than 5 minutes each. After each bass, I zero the volume, power off the amp, unplug, wipe it down and put it back. I'm looking at some overpriced Cort Fretless number hanging on the wall when the owner comes over to the amp, takes the cord and shoots me "the look". I jokingly asked him "am I done?" He says "Yeah, you're not gonna buy anything". I was amazed. At that point, the clerk comes over to him and starts to say something to the owner, but I stopped him. At that point I was done. I took my rag and went to Harry's.
I'll never go back there (and my kids won't go there either) - they could give away stuff, and I wouldn't take it.
Sorry for being so long winded, but that was therapeutic for me.
