I've had two dealings with BD, both admittedly a number of years ago now. The first was when I bought the rackmount kit for my Shuttle, the second was when I dropped off some of OldGit's basses for a commission sale.
Dealing 1 was all via phone and couldn't have gone better. Friendly, quick, perfect.
Dealing 2, a few years later, not so much... it went a bit like this (all statements are paraphrased but this is the general gist):
Me, arriving and walking in: *thinks* Wow, look at all this stuff... I have got to have a browse when this is sorted.
I approaching what I presumed to be the owner (might not have been, IDK), he's pottering about but doesn't appear to be massively busy. I am the only punter in the place.
Me: Hi, I've got those basses of Simon's, that his wife arranged to drop off with you?
Him: Yeah, whatever. *continues pottering*
Me, a bit taken aback: Oookay... shall I bring them in?
Him: Yeah, whatever. *continues pottering*
I bring them in, unassisted.
Me: So... do you want to check them out or, y'know, anything?
Him: S'pose. *starts unzipping gigbags*
Me, trying to make conversation: *points at Simon's Steinberger XL* Have you ever played one of these? I had a go, god it was so uncomforta...
Him: Yeah, whatever. *continues unpacking*
Me: Right... well... I'll leave you to it and you'll talk to Ros, yes?
Him: Yeah, whatever. *resumes pottering*
Me, walking out through door: You're welcome. *mentally flips massive bird in his direction*
I never did have that browse, and never will. It's too long a drive to take when there's every chance that I will be treated as an inconvenience when I get there. I never had a problem with making the equally long trek to the Bass Centre at Wapping, because I knew that there would be friendliness and free coffee and "is there anything you'd like to try?" waiting for me there.
