"Let me check the back."

I recently went shopping, I used to hate it, but now in some strange way it makes me feel important. I don't know. Anyway, I was looking for a tie, a narrow one. So I was in the store and they had about 4 different kinds of narrow ties. I liked one but there was a color I had in mind and they didn't have it, so I asked one of the workers if this was all the narrow ties they had. The lady said "Umm, I thought we had some more, let me check the back. Hold on one second." In my head, for the moment I actually thought there might be something "back there" and when she returned of course she said, "No, I'm sorry. This is all we have." I smiled and said thanks and then I thought to myself, when have I ever asked for something and the person said I'll go in the back and check and actually came back with it? Never. If they had it, it would be in the front. And then i started to think about when I worked in Sears selling treadmills, I would tell people all the time "I'll go back and check" knowing full well that it wasn't there but I just wanted to get away from them and sit in the back room and do nothing. I would literally sit in the corner of the storage room and stare at nothing for about 5 - 10 minutes and pretend I'm doing something. It just satisfies the customer and shows them that you tried. So the next time I go looking for something and it's not there, I'm going to ask someone if they can check the back and then leave before they return. Maybe I'll look from the outside and see if they try and find me in the store. I haven't decided yet if that's completely ridiculous, but I think it would be pretty funny to see.
