I come across this fairly routinely...someone signing in a store, getting coffee, whatever. Not every day but it's not rare. We don't live in an urban area anymore either. Do you live in a really tiny town, Jane?
It depends on what you consider tiny. The one I am in is about 13,000 with two even smaller ones that you have to look at a sign to know when you cross from one to the other (one, Central City, is north of Centralia and Wamac is south). The three and built up unincorporated area next to them is probably 15,000 or so in Southern Illinois.
I just thought of a time a few months ago when a guy that waited on me when buying pizza mentioned it (after I told why I had to have something written down). And he told me about his other job at an exercise place where several do use it.
