I was at Target Field 4/20 and didn't notice any problems as far as lines go for the men's restroom. I didn't realize until after I'd finished there was an additional set of urinals in part II of the room, but I didn't have a line to wait it in. I was in and out in and back to my seat in less than a 1/3 of an inning. Before the game might be an issue as people are slow to get to their seats.
Amateur! Seriously, you'd hope there would be something more to provoke this than getting hit.. in the shin.. with a breaking ball. Otherwise among baseball people, I'd guess Offerman goes out remembered as a stinkin' coward.
