Not to invade your post with my own story... but a similar thing happened to me once...
A few years back... I was squatting 455, and I got 3 reps... Not ATG or anything... but stopping at parallel for sure... Anyways this twink with no ounce of muscle, wearing spandex pants and looks EXACTLY like the Sherminator (From American Pie), comes up to me and goes "That doesn't even count!"
I was like "Excuse me?"
He goes, "You gotta go ATG man..."
I was like "I went to Parallel"
And he goes "Big Ron Coleman goes all the way down to the hole with 800 lbs!"
I was like "Well, with everything he's taking, he can do whatever the hell he wants"
And he's like "Oh bro, you think he's taking anything? I'm pretty sure he's 100% natural, man!"
I was like "Alright buddy, you have a good work out!" And I just walk away!!!
