I have two. I use both of them to mark our territory at the bar.
ON the bar, not on my head. It's kind of a lion marking his turf, or a dog, or a cat.
THIS area is CHEESEY, and not in an especially nice -way--more of a don't even think of bringing your bare bullshit/vikes smack...whatever here--we are drinking, now.
Fellow puker fans to right and left move them to
their "outside" in order to graphically establish the perimeter.
They are also pretty decent conversation pieces, because most had never actually seen one before. Most were surprised at how "substantial" they are---(most thought light foam-foam)
They are also handy in this instance because if the perimeter is wide enough (usually is) we cheesey types get the requisite number of TV's, including volume...in front of us --bartenders know this stuff here.
They do have real utility, if employed properly.
