Going off the deep end

[Homer]

So, my gf called me today and told me that she went to a rug store and informed the person working there that she was interested in something in a certain color. I guess this was a fancy store and she seemed out of her element or something, because he immediately said, "Maybe you should go to TJMaxx or Marshalls instead. Plus that way, you can at least walk out with a nice pair of shoes." Basically, he was condescending and sexist. I'm getting tired of people walking all over her and am about ready to snap. I'm tempted to head over there and do something, but I'm not sure what since I'm not a confrontational person. Anyway, I need some suggestions. Should I just punch a wall and grab a beer or should I go out of way to confront this piece of trash?

p.s. - Yes, I realize that this is insignificant and stuff like this happens to everyone, every single day, but I can't take it.
