No offence but its ALL about how you are treated.
I was looking for a suit for business reasons, and I walked into JC Penny planning on getting a good deal. I asked if they could help me (after standing there with them looking at me like I was stupid). They measure me, and say "Back against the far wall over there"(and she flicked her fingers in the ONLY direction towards the ONLY suits). I walked out and never went back. Now I went to Men's WearHouse, and they helped me get what I needed, and I got FANTASTIC treatement. I spent probobly $200 more, but I got it tailored, and they treated me like a human being.
Its always about how they treat you. If you are treated like an animal, why would you want to continue shopping there?
Its like in webhosting -- the customer buys and stays with you based on level of support, not just because its so cheap.
If you live based off of you don't care how you are treated, then I am sorry to say that you are missing out on life. Grantit you may not be there for the customer service, but you still want to be in a happy, good environment and know that they are there for you to help you with your needs.
They get payed to help the customer, not stand there and make sure you don't shoplift. Thats what security is for
