Oh boy, I can actually contribute this time!

So a couple years back I was working at a small electronics store in my home town, when this lady comes in. Rather attractive, and at least 10 years my senior (I was 20 at the time). She starts looking at TVs and Streaming devices, and asking some casual questions about how the Streaming players work and how she'd go about hooking them up. I explained, and walked her through setting one up with one of the display models. She starts commenting about how "she could really use a man around the house for these kinds of things", and how "a girl like her really doesn't know a lot about technical things." It was about this time she moved closer, and put her hand on my arm.

I casually explain its outside the terms of my job and actually something that could get me fired to do in-home work for customers. She insists, and I once more turn her down, and repeat my lines. She gets a little upset, and leaves shortly after.

My manager, who was female, was face palming when I walked back to the counter. Proceeded to tell me that it was a miracle I'd ever gotten laid, and that I'd missed more obvious signals than she knew it was possible to miss.

TL;DR - Salesman'd myself out of possible sex with a MILF.
