Granted, it's not unheard of, but still...
Maybe it's just me, but until recently, I'd never really thought of kids' games on the back of tray liners at burger joints. I remember such things at sit-down places when I was a kid, but not burger joints.
But recently, the place I work at started putting them there. Apparently, it's not as bad an idea as I'd otherwise be inclined to think.
I just hope it stays that way and doesn't wind up getting messy, is all.
