Next to the bagels is a bagel slicer, which I'm sure you've all seen. It bears a vague resemblance to a guillotine.
This morning I noticed there was half a bagel in the slicer.
As I sat looking up patient info on a lounge computer, I watched 3 docs come in for bagels. They each took the abandoned half out (which sounded hard as a rock when they set it on the counter), slice their own bagels, THEN PUT THE STALE HALF BACK IN THE SLICER!
It was still there when I went to round. For all I know it will be there when I retire.
