Fail to see how griping where dude ain’t hearing it matters except for guys here hearing it.
Honestly can’t think of any way I could’ve educated the guy unless he’d asked. What I did do was use 3 times his weight for my EZ curls where we were both viewing the same wall mirror. Maybe seeing my biceps under a heavy load inspired him a little but theres no way to get feedback on that.
I guess one good thing about it for me was seeing that I’m actually stronger than a skinny Asian dude lol. But whatever.
It’s of zero consequence and I’d handle it the same again - use some other way to get my workout done, not say a word out loud, and proceed to gripe to uninvolved third party internet meatheads, or maybe just keep it to myself cause the mental energy would serve me better elsewhere in life.
