I have worked in this industry on both sides of this planet since leaving university in 1994/95.
What I have enjoyed/enjoy the most is the relationships and friendships I've made along the way with people who started our interactions as potential clients.
I've enjoyed the freedom of not being commission-based which (in my opinion) has allowed me to select the products that suit my client's needs. I will also tell clients my personal preferences up front, and why.
However working in this industry (and retail in general) is getting harder and harder, and the fun factor and job satisfaction is not what it used to be, so to the OP, by all means if you are interested in getting into the industry, go for it, but don't stick around if you find it frustrating, it "can" burn you out.
I'll give you a current example of where this industry can be soul destroying...we have a client who came to the store months ago to listen to a brand we have exclusive here in WA. After getting the specific model in for him to listen to, followed by a lengthy demo and discussion we detailed a price, to which the client was unhappy with (despite this brand being currently cheaper in Australia then most of the bigger markets around the world, and this price being given before we even got the unit in for him to listen to!), and wanted to think about it (usually that's a sign of ringing around/emailing to get a better price). Some weeks later he came back and started up the same conversation with a colleague and wanted another listen. When he was told that we ended up selling this unit to another client he was perturbed as to why we would do such a thing. He then asked if we could get another unit in for him to listen to again (did I mention this "unit" isn't cheap?). We reluctantly agreed but now the customer hits my colleague hard for pricing by coming back with "confirmed" prices from interstate stores. When the demonstration unit came in, he then wanted to listen to two other units in the range that we didn't have (more expensive).
This back and forth about the 3 units for audition went on for a few weeks, but we refused to budge on our "fair" price. This "client" then began ringing around the various local stores looking to see if they could possibly get access to the brand, even to the point that one store made contact with us about supplying!
Right now this client has a price from the Eastern States that is his reference point (a stupidly cheap price for what the product is and commands) and is doing all he can to buy it cheaper, yet has no concern about the financial cost of us getting in the best part of $50,000 worth of product for him to audition (a second time). Don't get me wrong, we all tend to be self-centred when purchasing goods, after all we want a good price and be looked after. We have done nothing but entertain and help this client out, with ZERO reward for our efforts so far.
If this client was so serious about buying this amplifier, it would be better for him to hop on a plane and listen to all three in various stores in Melbourne, buy the one he wants and fly back. Instead we are being treated like a free advice bureau.
But, issues like that aside, its still fun. I get to play with some fantastic toys, and love discovering new music thanks to the people who walk through our door. The good days are great, the bad days, well, I go home and hope tomorrow is a great day!!
