The days of retailers hiring people who have a knowledge of or passion for what they are selling are long gone (though there are a few gemlike exceptions, Textile Traders in Midland and Zena's our local LQS). I always vote with my feet, and generally, politely let them know exactly why I won't be coming back, either there and then or by dropping the management a note. I would rather travel a few extra kms or pay a little more for good products along with good service.
