I have a feeling that when inconsiderate customers like you say you will never shop at their store again they breath a sigh of relief.

Retail is a hard business. People who work in a store have every right to go home at a decent hour. They didn't know you could do all your shopping in 5 minutes and frankly, I don't believe you can.

In any case, try and put yourself in their shoes. Maybe you could shop in 5 minutes but that would not leave them enough time to ring you up, bag your purchases and get you out the door by their quitting time.

Now are you willing to pay them overtime? Because I guarantee their employer isn't. OT has to be approved beforehand. So from the salesperson's point of view you are asking them to work for free just to satisfy your selfish needs.

People like you make people in retail cranky. Stop spoiling it for the rest of us more considerate shoppers.
