1. Management is very inflexible with scheduling
2. Management forces you to sell overpriced attachments on all items, like warranties, antivirus, and other software. If you don't, you get reprimanded and your pay gets cut (your commission is based on how much you can upsell customers into buying software, warranties, and credit cards).
3. Pay is based on how much you scam customers to buy things they don't really need.
