Yea, I was never exactly in sales (Geek Squad in store employee is the closest I ever came) but I remember thinking everyone who was like lets get rid of commission in retail sales were very mislead. I still remember the difference in Sears employees in the 90s when I first got a PC and the salesman actually knew to look at the box of the game I was trying to buy and make sure it'd run on my PC before selling it to me. I also remember them knowing about the stuff they sold. This is because with commission, even in small towns you could make a career of it and you'd have actual experienced staff in the stores. As far as I could ever tell, the good salespeople wanted you to trust them, and not to just make a one time huge sale - they wanted you to come back again and again.

Once they all went to non-commission, I recall that being a "selling point" of the stores, but now all you had was a rotating cast of highschool and college summer workers who cared exactly as much as minimum wage paid them to care... i.e. not at all. And they occasionally became unable to even read the boxes they were "selling". It turned them into less efficient cash register attendants.
