Pros
Get a decent discount, work with some very nice people, try to accommodate your schedule unless it is in the Month of December:) Staying open for Black Friday all day and night like all the loser stores such as *mart, etc.
Cons
I work as a cashier, and these are the duties of a person getting just above minimum wage. Greet customers and ask if they found everything ok, get them to sign up for a scorecard( a free loyalty card), try to upsell a protection plan if available on their product(s), try to get them to open a credit card, take returns, use coupons that only work for 1/2 of our clothing and merchandizing, explain why the other half do not accept coupons, turn away coupons received on the internet from unauthorized places, answer the phone, not allowed to drink water at the front line, and do it all within 1-2 minutes because of the constant understaffing, and fold cloths if you happen to get a breather.
