Maybe I'm in the minority.
When I owned a Suzuki, I went to their parts counter a bit. They have a pretty good stock of parts and I found the parts guys helpful and willing to chat. (Tri-City was my 'home' shop - and they're great, Josh and Patti were super-helpful but Two Wheel must have twice the parts.)
They were really cool about letting me sit on bikes in the showroom too.
I didn't buy any big-ticket items (bike or gear), or have them work on my bikes. I'd go back to their parts counter if I owned a Suzuki or Kawasaki. Granted, there's a pretty select number of people I'd have work on my bike... and usually, for every shop, there's a horror story.
