We had a Mr. Helmet situation in our club, and the guy was strongly encouraged not to come back, for his own sake and for the sake of others riding w/him.
Before we headed out on a 4 star (14+mph) ride, our Mr Helmet, I'll call him Mr. Inappropriate, asks me to check his blood pressure. He said he just checked it at Walmart, and it was 240/140. I said, sure I'll check it and if it's even remotely that high, you should not be riding. He said, "Oh forget it I was just kidding". He would not let me check his pressure and we proceeded to ride.
Not once, not twice, at least five times he rode up behind me and said "I like the view behind you Colleen, I mean, I really like the view". Ok, ya know, I can take a joke but he would not let up and after about the third time I was thinking he was really off the wall and making me feel uncomfortable. (the view is NOT that great, let me assure you)
At the end of the ride, he asks me (again) to check his blood pressure. It was sky high 230/140's. He then admitted his pressure really was 240/140 before the ride and he just didn't want me to tell him not to ride. I had an obligation to tell him he was being extremely foolish to go on a challenging ride (he's an inexpereinced, new rider) in hot weather knowing his blood pressure is out of control. I asked him to promise me to seek medical attention the next day, to which he agreed.
Then he joins us for pizza after and lies to the waitress to get a free order of cheese bread! After a 45 second conversation at dinner with Mr Inappropriate I realize he does not have all his oars in the water, if you know what I mean. His friend that brought him apologized for bringing him on a ride, and didn't really know how serious this guy's psych problems (apparently) are. He will not be invited back to ride as he poses a danger to himself and others. What if he had stroked out on a ride? It's a wonder he didn't.
