Three chefs

We found these three chefs taking a midday break.  
Actually, I would guess two chefs and a cook?

The one on the left looks dressed as a chef,
and perhaps the man in the middle as well.
I wondered if the one on the right serves the plates?
Each of them has a white scarf or handkerchief 
tied in a short knot around his neck.

Ah, la vie quotidienne!
