I've been ignored in T&Co in different locations too...
At the Old Orchard/Skokie, IL location if I go in either on my own or with a female friend, we are totally and completely ignored. And I don't go shopping in sweats, I am usually dressed fairly nicely. My friend & I always know it is because we're two girls shopping together and not with a guy, so they figure we're not going to be buying anything. Big mistakes. Even if we're not buying and want to try something on... that usually means we're sending our BFs back and a bad experience may make us choose something else.
Also, we'd go in college to the Chevy Chase, MD location and it would usually be me and other girls going in to chip in for a gift for a friend and we'd totally be ignored and we'd have to go after the SAs to make a purchase or be able to look at things.
But then... in either of those stores, if I'm with my bf, brother or dad.... you better believe there is an SA waiting on us as soon as we get to the counter. It is pretty incredible.
