Well the issue is compounded by the fact there are no White Castles near here. So every time I've eaten it, it's been in the middle of a 3hr or longer road trip. None of my current vehicles have a toilet behind the steering wheel, so it makes for a long, and sometimes complicated trip home. I've never been a fan of brown interior, so I just skip the WC now.
White Castle calls them sliders because that's how they go in, and how they come out!
