He got banned because he was taking too much of our time. Then there are people who buy and return and buy and return. We've banned customers who regularly order a whole bunch of stuff, and then return almost all of it. One lady would order about 20 dresses and then return 19 of them, some of them still unopened. Overall I'd say I've noticed a change in recent years in the customers.
People are more impatient now.
They expect so much for nothing. They can be so unreasonable. It's always someone else's fault and it has to be made good. They're into instant gratification. It's very reasonable to return something if it arrives too late, and have the return shipping paid for.
