Make the sign of the cross and say grace when eating out and see how people react to you.
I do that all the time. No one has ever given me a dirty look. I do it for Jesus, but also it just may remind another person to think of Jesus, however briefly.
My husband and I always do. Of course, we don’t really care whether anyone likes it or not (and we don’t eat out much either but oh well lol). We also always abstain from meat on Fridays but we’ve done that for quite a while, and I did for years in my other life as Orthodox.

I do that, but I don’t see how people react. I say grace, then I eat. Their reaction (if any) is their own affair.
