...do you leave without buying it?

The Motherhood Maternity in my hood sucks! It's tiny, the manager is obnoxious and the other chick who works there is not helpful at all. Last night I went in hoping to buy a shirt but they didn't have the right size/color. I asked the girl working if the one up high on a mannequin was a small; she said no. This morning I went back in for a peek and asked if they had the size/color I wanted, which the manager immediately pulled off the mannequin...I would have bought it yesterday and specifically asked about that, argh! But now I'm torn on color again since I didn't think the original choice was an option. I asked a question about a promotion and she (the manager) was rude about it, then tried to sell me other things instead (you're shopping for shirts? how about bras instead?) and I got annoyed and left. I have been in 3 times this week hoping to buy something, but either they're not smart at all (likely true) or they don't want my money! So I drove through McDonald's and spent $$ there instead. I hate crappy salespeople! I think it especially annoys me because I worked in retail for so long.
