Years ago while I was stationed at Fort Campbell, I lost one of the eyeglass screws that held the lenses in. We were going through an intensive inspection and I had a million things to do and 122 soldiers to look after, so I bolted to the clinic.
As I was walking in, I remembered that every other time I'd been there, it involved a long wait before they called you back, so I decided I try to speed things up. As soon as I walked in, I headed straight for the receptionist who turned out to be a drop dead gorgeous blond, with a body to match, but the biggest thing on my mind was to get back to the unit as soon as I could.
When she asked what they could do for me, I just blurted out "what are the chances of me talking you out of a screw real quick?"
Just as I realized what I'd said, she stood up and gave me one of those looks that should have killed me right on the spot for a minute or so, then asked me who I thought I was.
As soon as I could get the eyeglasses out of my pocket and show her the problem, she calmed down, sent me back immediately to the techs, dropped her head on the desk and started laughing her butt off. The techs quickly took care of me and as I was leaving, I stopped to apologize for my actions. She told me that her first thought was that she'd never heard a pick up line like that and her second thought was that it was the worst pick up line she'd ever heard.
I felt so bad about it throughout the day that I sent her a small bouquet with a written apology. After all that, we got to be pretty fair friends, I even met her a few times for a drink or so after work, but sadly enough that was the extent of it.
