Pros
Other salespeople are subpar at best, including quite a few store managers, coasting along so competition isn't an issue. Of course, the good ones know who they are.
Cons
Managers will not reward good salespeople with more hours and/or raises. It's no wonder there is a revolving door for actual sales talent and where the most agreeable and cliquey-collective types get to stay. The only reason Luxottica and by extension Ray-bans, Oakley, and all other in-house brands do well are because of the ridiculous, 1000% markups on the products. When your gross profit margin per unit of Ray-ban is 90%, you don't really need good salespeople. Commission is 1%. On a 200-300 dollar pair of Ray-bans, that's 2-3 dollars. I once sold 14 pairs of sunglasses in a single transaction, and my commission was like 25 bucks. It's criminal.
