My family and I ran into a bit of a snafu this week when we realized I did not have a current vehicle sticker on my car, even though I'd paid for one. When I went in to the DMV to investigate, it turned out that they had tried to send it to me, but it had apparently been marked as undeliverable and had been returned. Considering I've been at my current address for several years and have had no prior issues receiving mailings from the DMV, I have no idea what went wrong. (Well, I have some ideas, but that's getting into politics.) The issue could be with the DMV, but I think it could be the mail service.
It occurred to me that at least this incident might generate story ideas. What's the one public service you would want to keep running in a crisis? Which two public services are most likely to clash with each other? Which ones would be the funniest? Please leave your ideas in the comments.
