Co-workers drink with their meal.
Many think it's not a meal without the right wine pairing. A few don't drink wine, but just water or something non-alcoholic.
I posted on here recently that teachers at my high school could pick up little carafes of red or white in the cafeteria lunch line, which was open to both students and staff.
My father, before he retired, had two hour lunches with his colleagues, in which they talked of nothing by food, recipes, food prep, shopping for food, wine, alcohol, etc. And these were all men.
