I understand the recon mission followed by the swift bombing run. But I'll tell you how I crossed the line.
I was on a business trip and went into a consignment store. There was this pink blouse that I took a liking to, but I wanted to try it on before buying. The dressing room was monitored, you know, where they give you a tag representing the number of items you took into the dressing room. I figured the girl would inspect, and ask me if I knew I was trying on a woman's blouse. Finally after circling the blouse for about a half an hour, I took a fearless pill, so to speak, and took the blouse to the dressing room. She say how many; I said one. She didn't even look at it or check the count. BTW, it didn't fit.
Ten minutes later, next store. On the sale rack was a beautiful pair of satin PJ bottoms. I took them and asked the SA if it was OK to try them on. She said sure, and showed me to a dressing room. Once I decided to buy it, she tried to find a matching top for me to buy and she tried to sell me some other things.
So, as long as you come with green paper with pictures of dead presidents on it, no one cares. Well, not no one; the are some exceptions, but mostly no one.
And it's a great excuse to use even if your wife *really* isn't there.
And don't forget Christmas shopping season is coming up soon. The perfect excuse for a man to buy just about anything for his girl.
