Is it okay if I go the bathroom or get another beer while the commercials play? If so, why?

Thats like saying the grocery store is ok with me eating some of the grapes while I shop so they must be ok with me walking out without paying for my groceries.

I’m not trying to be obtuse here. I really want to understand some sort of reasonable moral justification for actively avoiding paying for a service that you are using / circumventing the mechanism by which the business makes money.

> circumventing the mechanism by which the business makes money

This is generally of no interest to consumers.
