Hijacking a bit, but at least it concerns grammar ...
There's a sign when one exits the Murphy gas station at the Madison (AL) Wal Mart on Madison Boulevard that reads something to the effect "NO DELIVERY'S ALLOWED". This is a professionally printed sign, not some hand-lettered thing.
I'm not sure how the trend of forming plurals by use of an apostrophe ever started, but it seems about half the people do it nowadays. It's one of those things that's very irritating, like squeaky chalk on a blackboard.
