"Real customer service" isn't taking returns willy-nilly. It's having a fair policy and implementing it equally. A 30 day return policy is more than fair for a company that's in the business of selling seasonal clothing. Anything longer than 30 days is a gift... a gift that people often seem to abuse.
The "customer is always right" adage has gotten to too many people's heads -- the customer isn't always right. In fact, the customer is often down right wrong, rude, disrespectful, preposterous and disagreeable.
Oh, in case you're wondering -- I don't work in retail -- I just shop in retail and am often bewildered by the increased sense of self-entitlement that people try to inflict upon those around them. From the divas who toss all the clothing they try on onto the floor (including the one I witnessed peeing on a pile of new clothing in the dressing room across from me), to the woman who's at the register holding everyone up while arguing that she should be able to return her 6 month old items from two seasons past -- it affects all of us (from something as simple as ended up going home with clothing that's been tried on and stepped on, to having our time wasted, to paying higher prices because of loss).
It's not difficult to learn the follow the rules -- even a 5 year old can do it -- provided they've been raised properly.
