Why does opinionated friend reject my friendly tip?

Friendly tip? Really? Not being able to breathe is an absolutely TERRIFYING experience. Your friend was freaked out, gasping for air and probably saying a silent prayer of thanks that he got the food out of his throat - and you come over offering a "friendly tip"? You should have whacked him on the back and brought him a glass of water. I probably would have told you to get stuffed, and thoroughly MEANT it.

It was a thoughtless and silly move on your part. I know you didn't intend to come off as a know-it-all or make it all about you, but that's exactly what you did. Your friend nearly choked. And you get offended because he doesn't care to hear what COULD have saved his neck? Your "friendly tip" was useless at that point anyway.

You owe him an apology. Seriously.

Great tip, hope I never need it, but thanks, I will remember that!!

My only guess is that he was in distress and did not want any help as perhaps he had it under control. Choking is scary and it is really hard to talk or communicate while in that state. He was unreceptive to hear any advise, that is why he rejected it. That would be your key to back off.

It would have been more productive to simply tell him what to do in his distress. Maybe he thought you were going to offer some advice about what book to read or some other irrelevant thing.

My unsolicited advice: Learn about the Heimlich maneuver.

Please don't listen To this person. As a paramedic and a nurse I can tell you that this not an effective way to stop choking but will make it worse.

I don't know where they got this info but it is totally wrong and could kill someone
