Is this a northern thing? I grew up bowling in Alabama, have bowled in Georgia and Florida and now I'm bowling in Tennessee. I've yet to encounter anything other than 1-lane courtesy yet.
I would have loved for a lot of the 2+ people to have learned to bowl where I did -- Monroe Lanes in Monroeville, Ala. Ten lanes, ball returns above ground, juke box playing the same six records over and over (including the live version of Chuck Berry's "My Ding-A-Ling") during league, 1-lane courtesy, lanes breaking down constantly with the lane mechanic, who was also on a team, having to run down the access channels next to lanes one and eight.
You bowl in that for a couple of years and you'll be able to bowl in the middle of a stampede of goats.
