Two pissed women

The last thing you should want when you are in the electronics business is two extremely pissed off women returning things.
My Girlfriend and I got her some electronics from a big chain store. The first time we were so focused on what we had to do and the excitement that we were able to pick up one of the hot items that we didn't notice there was something wrong...at first. Several hours later we did notice however.
I called the store to inform them of the problem and that we were bringing the laptop back for an exchange. The man I spoke to not once or twice but three times got rude with me. Or at the least he walked all the way up to the line of being rude without quite crossing it.
He even had the nerve to lie to me about who the managers on duty were.
Now, I will admit that I am not the be-all-know-all about computers or electronics in general. But I do know quite a bit about things and I do not take well to someone talking to me like I don't know how to find the power button on the device -- or like I can't distinguish a screen that demands a password to even be able to login and a screen asking for a wifi password!
When we walked into the store we immediately asked for a manager and got the problem taken care of. Please keep in mind that I have left several things out of this story for simplicity sake (I mean, do you really want to hear me rant about how over the phone said jerk refused to even hold another computer for us even though we were on route to do an exchange, or even check to see if there WERE any still there or how when I walked in I walked directly over there and managed to grab the last one?).
The manager was excellent, and it was to the benefit of the store that he was otherwise my friend would have   simply returned the item and bought it online.
Too many times these days many stores don't seem to bother with customer service and too many employees seem to have decided that they don't have to worry about treating the customers with respect and this makes me not only sad but really pissed off.
