Not my foot, this time, but my sister's.
Many years ago, my sister and i were eating in a restaurant that was popular with the older set. It was quite loud inside, partly because of so many people and also because they were talking very loudly to each other. My sister had been a RN and worked many shift at ER section of the hospital, and had many stories, some pretty gruesome and some very funny. She started out by telling of an unconscious individual that had come into emergency room. She did the initial exam and she had a pretty good idea he was faking it and just in there for drugs. During the telling of her story, she kept having to raise voice louder and louder, to be heard over all the other conversations that were taking place. So she told me, she did the usual "test" they use to weed out the druggies. One test is to identify whether the person is a "back stroker" or not. While the individual is laying on their back, they will raise their hand and arm, up in the air above their face, and release it. If the person's hand smacks them in the face, they're likely unconscious, otherwise, the arm and hand will miraculously miss their face and end up next to them, kind of like they were doing a back stroke, another is the use their finger and flick the person in the throat kinda hard, that's "wakes" the fakers up real quick. Now this guy was a pro, she did all her "test" and this guy wouldn't break, obviously very experience with the whole thing. But something made her think he was faking it. By now it's gotten very loud in the restaurant and she raises her voice even more. She said, of course they didn't have his name so the chart said John Doe, but when the doctor came in to start exam, my sister said we have a DIL DOE....at the exact time, when every conversation in the room had stop, so not a sound, except my sister's voice, echoing off the walls.
