It's like that in all the big chain music stores; Guitar Center, Sam Ash, etc. You can certainly tell the posers and wanna-bees from the seasoned musicians. One group will play as fast and as loud on as many instruments as they can get away with. The other group pretty much knows what they want and will usually walk in, buy it, and walk out. Sure, they might plug it in and play a few notes to be sure it's not a DOA and the neck/bridge/nut setup is somewhere close. But you don't see "real" musicians hanging around in music stores all day banging on instruments.
Before I get into trouble, let me qualify that last statement.
I have a friend who works at Buffalo Brothers Guitar
in Carlsbad (San Diego area) and when I visit the store I may spend a couple of hours in there plinking on a few of the exquisite acoustic instruments they have there and visiting with my friend. But where else are you going to get to try out $6000 - $12,000 and up guitars? I'll strum a couple chords, gingerly put it down, and say, "Wow! That's nice!", not wanting to scratch it.
Thank you for your indulgence,
