Warning: There is a chance, small but perceptible, that a complete stranger will hug you at the Post Sports Bar & Grill. And we're not talking about some half-assed "bro" hug, either, but a full-fledged, diaphragm-crushing bear hug. It happened to a friend of ours. He'd come to the Post on a Sunday to watch his hometown football team play its archrival. The bar was packed with other NFL expats and fantasy-football geeks watching the games on one of the Post's high-def flat-screens, but our friend was pretty sure he was the only fan of his team there — until, that is, his team scored, and a man seated nearby erupted with a bellowing cheer. OK, so it turns out this stranger wasn't a fan of our friend's team, but he did have money on the game, and that (plus a few beers) was enough to cement the bond. When our friend's team pulled off a last-minute comeback, the stranger grabbed him in both arms, and the two jumped up and down with joy — a celebration that might have been more pleasant had our friend not already gorged on the Post's tasty bar grub.
