Speaking as a guy, a nice thing about the local JC Penney is that nobody seems to want to help you. I went in there to look at suits, and nobody bothered me the whole time, which was nice. I’ll ask for help if I need it.
Conversely, I went to the local Dillards to look at suits, and right away someone was all over me trying to make suggestions. Personally I don’t like that. I don’t mind if someone introduces themselves, but then (IMHO) they should leave you alone. Personally I’m much more likely to buy something if you give me time to compare things and make up my own mind instead of trying to sell me on something. As I wrote in A Survival Guide for New Consultants, a good salesperson is really a buyer’s assistant, and sometimes that means giving the buyer space and time to think.
(I left the Dillards pretty quick when it became apparent they weren’t going to leave me alone.)
