People really don't know how to handle change these days. It's kind of sad. I'll be the first to admit though when I worked retail it took a bit to get fast at it. It's one of those things where you can be trained, but until you are on the job with the fast pace you don't really get it I think. The hot dogs look amazing. We have a few of these "gourmet" style hot dog places popping up and they have some pretty impressive flavors.
