You know, that is not a bad idea.
I mean, many bars and clubs have a set night for "SIN"-Service Industry Workers, where drinks and sometimes food is reduced for the workers in the industry.
They have Ladies Night, Mens Night..
Even though it is mostly bars that do it, it possibly could work in a restaurant for the working class stiff.

You could even call it "hump day" special in addition to your rendering, Fieldthistle..
Maybe a percentage off or a non-alcholic beverage with the meal-possibilities can be endless.
I know there are many restaurants that have coupons, but most of them are usually for buy 1, get 50% off another meal.
I am single, I dont have another person with me.
Does not do me any good.
You never know.
I mean we get a little stretched between paydays some times.
