Where is classism found?

In my opinion, classism can be found just about anywhere, even in the the tax code. It is seen in malls, in grocery stores, just about anywhere.  By comparison if you shop at a store that is frequented by a wealthy clientele you will notice that the customer service is much more friendly, and the overall shopping experience is better then shopping at, lets say, TJ Maxx. Classism is most commonly used by treating someone wealthy better than someone who is poor. If I was to pull into a bank in a Mercedes, then walk into the bank with a designer suit on, do you think they'd treat me the same way if I walked in looking like I was homeless? Most likely not.
