PBA: There are certain cases of Mar’is Ayin which are pure Issurei D’Rabannan and apply regardless of common sense. There are some cases which might be Muttar for common sense. The Acharonim discuss what applies where.
Agreed. That is not the case here.
There is a separate Halachic issue of “Vih’yisem N’kiyim Meihashem Umiyisrael” which also tells us to avoid things that will allow people to be Chosheid us or that they would learn to do wrong from us. Common sense should apply to these.
So far so good.
But common sense doesn’t mean that “I know the guy is frum, therefore he is probably doing something Muttar.” It’s more like something where the general assumption of using that object could be for something Muttar.

I would think that going into a McDonald’s in the city would be Assur from this but on a rest stop on the highway would be okay.
Maybe. Maybe not. I think McDonald’s in the city is fine. It looks like neither of us knows and we are just zugging boich svaros.
And I like my boich.
