AutoZone review: rude employee

This woman employee was very rude to my father. No other customer was present at the time of our arrival. She persisted to act Inconvenienced by assisting us. We had trouble finding a specific oil filter and just asked if she could locate it. She stated, " I could have done that the 1st time & saved us both time." After her comment we just said, " ok, don't get mad"... The female employee responded, " I'm not mad, it's just my face. Do you have a problem with it?" This woman seemed very aggressive and agitated just by us asking for assistance. I hope she doesn't treat other customers this way. I wouldn't want her to be hostile towards others.
