Although I mostly work ER these days in my earlier career I was primarily a clinic based family physician. And I still do the rare day in clinic when the local outfit needs a hand due to vacations and such.
Usually there are Dairy Queen Dilly bars in the break room when I arrive. It's kind of in my contract.
It all started a few years back when I was filling in for the clinic on a more regular basis. At the end of the summer the work load was back to normal levels for them and I went back to doing ER. But oddly there was an error in the payroll department and they kept paying me. This is all electronic deposits these days so it took a number of months before I figured out what was going on.
I tried to give them their money back. Its not after all as if I had blown it all on rum and wenches. They refused. Told me it would screw up their accounting system I guess.
Instead they said I had to keep working for them. Until we were square.
So, in the first decade of the 21st century I was an Indentured Servant, working off my debts. I like these folks so that was not really a problem, but I told them that they had better have Dilly Bars for me when I worked, as they were not paying me any other way!
That was some years ago. My clinic shifts are infrequent these days as their staffing situation has improved and I am actively trying to avoid extra work.
But sometimes, not always, but sometimes, when I do turn up Administration remembers our informal arrangement and when I peek in the freezer I see a couple of boxes of Dillys!
