What is it that guys look for in a serious cloths shopping experience?

When you are out to do a bit of cloths shopping, what is it do you look for? Anything from the customer service you expect, to the items you want to find in the store, to the overall decor of the place. Please feel free to put as much input in as possible and optionally include how you would best describe your clothing style as well as where your from. I would really appreciate the help guys!|||When straight guys go clothes shopping, they just want to do it as fast as they can so they can get back to eating/playing video games/masturbating.|||I like to shop in places that are a little classier that sell suits, ties, dress shirts, etc. As for customer services, usually since i'm a little younger then other people going into those shops i feel like i'm not taken seriously and thus the customer service isn't as helpful or they don't even bother to ask "is there anything that you are looking for?" in a casual wear outside, I either wear athletic wear or something like a short sleaved dress shirt with a sweater vest or something. i like Asics, but its a very hard brand to find actual atheltic wear|||I always look for a good selection of graphic tees, both long sleeve and short. Long sleeves can be just plain balck because i usually wear a long sleeve tee with a short sleeve overtop. Also, I'm very interested in black dress shirts with some sort of design on them - so it's kinda classy i guess but casual at the same time.
