I've often found hifi stores difficult places to shop. Every review or advice you read always talks about 'auditioning' whatever products you're thinking of buying, but really, who actually manages to find a store that a) has everything in stock and b) is willing to go to the hassle of setting stuff up for you?
OK they might turn the volume up a bit on a system that happens to be on display, but that's about it.
This supposes you can find a member of staff to actually serve you. I've left countless shops empty handed because the staff always seem very busy doing nothing in particular. I've worked in retail before and really, it is possible to serve more than one person at a time, and you don't need all of your staff to serve one person!!
OK this is a bit of a rant, but, I popped into my local Richer's last night. I'm in the market for new speakers and whilst I'm thinking of buying s/h, as they have a sale on I thought I'd have a look. Same thing. In fact one salesman kept asking me to move out of the way whilst he was showing another guy (who spent most of the time ignoring him while texting on his phone) some iphone docks. They asked me to move out of the way three times! Not once did he think to ask if I needed help or to call one of his colleagues over.
Another guy was at the counter but then disappeared to the back room - great when you know there are customers to be served in the shop.
Honestly I sometimes think the demise of the high street is well deserved!
