When it comes to poaching, the time honored approaches are best.

Point behind the grill master and say, "Ooooohhhhh! Beeeerrrrr!" when
you notice his bottle is empty.

Or perhaps, "WOW, would you look at the rack on that babe!" whether he
thinks he's looking for a stacked babe or a gal carrying some more
grilling gear, he'll look.

And then you grab a brat or a burger or a chop and split.

Oh, wait... that would be "poaching from the grill" and this is
"poaching on the grill."

Never mind....
