I went to an antique store today where there was no one on duty. We were there, browsing and I found a book I wanted.
There was a back room, a big one, with a door open out the back. There seemed to be a complex back there. Who knows?
Way, way back somewhere I could hear some clunking around. So I gave it one holler ... and no one answered.
We went back up front. (The back door had a sign on it, something to the effect of if you want to see back here, ask the guy.)
No one ever came. And I didn't have exact change. So I wrote the fact that I bought a book and the item number on a card and left $5. (The book was marked $4.00).
Anyway, there's a first time for everything. A self-serve antique store!
