Back in the 60's, you were allowed to bring in your own 6 packs. One game, my friend, Joe M, brought in a keg of beer & plopped it on to a seat between him & his friend. Almost immediately, a fan protested that " you can't put that keg on a seat ". Whereupon, Joe M reached into his pocket & produced a paid ticket for the keg. Oh Joe, you were a character. God rest your soul.
