How many times can u visit a hifi store before it annoys the store if u plan on a purchase

Just post the rules for those pesky customers on the door. Problem  solved.

I remember back in 1977 going to Lyric HIFi in Manhattan to buy a Dynavector 20B cartridge. Mike Kaye owned the store then. After sizing me up as someone not likely to spend thousands he made me wait in the vestibule while he went to fetch the cartridge. Apparently this was his behavior if he didn’t like the cut of your jib.

I managed a stereo store back in the mid-1970s and we had several types of "regulars." 

• Those who bought piecemeal, coming in to buy a single component as their budget allowed.
• Those who stopped by on a regular basis to check out the new brands or models that we'd picked up.
• Those who were interested in audio as a hobby and would stop by to chat. These people generally fell into one of two categories. There were those who were enjoyable and courteous and understood we had a business to run so never took us away from customers there to buy.  They were always welcome in our store. Then there were the arrogant jerks that seemed more interested in arguing, belittling, wasting time and interfering with sales.  Guess what we thought about them!

So, how often are you welcome at a store? It depends on you. (Of course, there is no shortage of arrogant jerk audio store owners and salespeople, but it shouldn't be too hard to figure out you don't want to spend time there.)

+1 @celtic66  You get it.  Cheers
