Bathroom

Yesterday I went to Costco to get a few items. As usual, I browsed through the clothing area where I have found some great clothes in the past and am usually pretty lucky in picking the right size. Yesteday, I noticed they were selling bras...2 in a package for $25. Now, if you are a woman, you know that A) That's a good price for 2 bras B) It is difficult to buy a bra without trying it on. So, I chose what I thought would fit and seeing as I needed to go to the bathroom anyway, would try one on after I paid for it and if I needed to change the size could do so without driving the 20 minutes back to exchange it. As they were packing up my things, I asked if they could leave that item on top as I was going to take it to the bathroom with me. "Oh, you can't. You can't take any merchandise into the bathroom" What?...now, correct me if I'm wrong. I have purchased this, paid cash for it and I can't take it into the bathroom with me. I was very peeved. I'm irritated that they were basically telling me what I could and could not do in the bathroom. I actually told them that then I could go to my van, take the bra with my receipt, put it in my purse, come back in and go to the bathroom..."you can't do that" Oh really....watch me!
Feeling a little guilty about raising a stink,I took my cart to the van and I shimmied the bra on in the backseat of my van that has tinted windows....it fit perfectly. I drove home still having to go to the bathroom and still irritated that I didn't prove my point.
