Should fast food workers question a customer when they ask for condiments?

I was at Long John Silvers (drive-thru) and the tattoo , lip pierced freak of nature girl asked what sauce would I like. I named about 5 different ones and she gave me an attitude and said, "what are you doing , stocking up your fridge?"......WTH? The food is expensive enough, if I want some of each of the sauce, should I get berated over it?
