I used to work at REI. I've also worked for many years for EMS. I found the experience as an REI employee both fun and horrowing at the same time. (Working for EMS was much better.)
On the one hand you get to meet alot of people passionate about the outdoors, and who are doing lots of cool stuff! You try to give them the best service you can. Sometimes you dont know everything.
On the other hand, I was making 5.25 an hour! I could not possibly make ends meet in the real world. My managers made around 20k to 22k a year. I am not sure how they made ends meet either. The good thing is outdoor retail sales people tend to take the shit more seriously than, say, someone at Payless Shoes. The reality is that you still don't retain particularly good help for a low wage - these are high school and college students, or part-timers on the weekend working for the discount, by and large.
I still go to REI. However, my purchases there have gone down about 50% over the last two years, as I find other, better, places to shop - both locally and online. My purchases at REI these days are pretty much B93'ed items and really basic stuff like Nalgene bottles.
I can get Clif Shots and Clif Bars cheaper at Trader Joes.
I can get climbing equipment online and at MEC.
I get real technical outerwear from shops like PMS, Patagonia, and FF.
I get alot of items from CASCADECLIMBERS.COM Yard Sale!
I get some things from Second Bounce, where it is invariably cheaper used, and still very servicable.
