Used to work there during college.
If we didn’t sell enough PSPs (extended warranties), we were not allowed to leave at our scheduled time.
Also, we moved all the laptop inventory to the back of the store, so if a customer wanted to buy a laptop that was in stock, but did not want to purchase an extended warranty, we were instructed to lie to the customer and say it was out-of-stock.
Also, the whole incentivized FBI Geek Squad informant deal was a bit immoral, too, IMHO.
