What's your experience with snooty HiFi salesmen?

I began my Hifi journey in 1976 at a shop in Birmingham MI called Audio Dimensions. He was a Magnapan and ARC dealer who was kind to a 15 year old kid who bought a set of MG 1s with paper route money. The ARC amps he carried were about $4K back then- a LOT of money in 1976. In the beginning I drove my MG 1s with an old Fisher Studio Standard integrated amp. Since those lovely innocent days I have encountered some real buttholes. They act like they are doing me a favor as they quiz me about what gear I have and if I'm listening to "approved" recordings. Needless to say I don't buy from those guys. Several wives and businesses later I'm back into the hobby with a much vengeance as a 61 year old  can muster given only so many free hours in a day and only so much cash to apply due to my other vices: Classic cars and salt water fishing. 

Have you ever encountered a really good or really bad dealer (or employee) that changed your buying actions?

Darko posted a video on this topic which I found really enjoyable. Many of you have already seen it but for those (like me) who discovered it much later here's the link:
