Unless there was a Hummer H1 in that middle spot when they got there.
I have had that happen to me. Park in the last spot in the lot in between what is there. Come out a bit later to find every body else is in straight now and I am taking up parts of 2 or 3 spaces.
I was driving the F250 Super Cab Long bed right after I got to Portland. They have tiny little parking spots at some of the older stores here so you park in the middle of 4 spots and endure the stares and glares.
If you try to park in one spot the wheels are on both stripes and you are a space and a half long! The Suburbs are better though.
