the denial of divers that they are bent is VERY common.. Very
In the Caymans when I was an Instructor back in the 90's it was more normal for people to insist they were OK when they obviously weren't than say 'hey, i don't feel great" and of those that did say that, 99% of the time it was a woman, not a guy. Guys almost always would argue with us when we expressed concern, suggested oxygen, go to the hospital etc. It was not uncommon to have a diver that you would almost forced to go on oxygen on the boat, refuse to go to the hospital, get mad at you for trying to make them go and then the next day when you come to work find out they did in fact go at midnight when the pain/symptoms got unbearable. As a volunteer chamber attendant, between 10pm and 3 am and you get a call it was a guy that wouldn't listen to their body earlier or their instructor/divemaster/spouse/travelling companions that they were likely bent. Just saying.
Now, the amount of folks that would argue with you they weren't bent when trying to get them to breath oxygen, go to the hospital etc and then went 6-10 hrs later when in much worse shape that ended up blaming you for bending them, not being forceful enough (and have had an ambulance at the shop and they refuse to get in the darn thing, then get mad you didn't force them) wasn't a zero either.
