Wolf,
I like asyyeger’s idea, but I highly doubt there’s a chillul Hashem since people saw you walking out with an obviously paid for meal, and you most likely didn’t have a guilty look on your face when you walked out.
Homeowner,
1) There is Chillul Hashem with Jews
2) There is an inyan of maris ayin and “v’hiyisem nikiyim” despite the obligation to be dan l’kaf z’chus.
