Salty, click on and read the OP's link. You OBVIOUSLY missed this part of it if you did so:
"Trump’s height and weight were "pre-reported" to speed up the booking process."
In case you don't understand what that means, that fat fuck never stepped foot on a scale.
You ask why not put him on a scale? They just wanted to book his sorry ass and probably laughed at the absurdity of his weight claim. What do they care? It only helps them regarding his complete lack of credibility.
