Meno, true, but what I meant is that people are more likely to end up with a problem with other pas haba b’kisnim since they usually don’t bentch (and didn’t wash and say hamotzi before they started), and that is a bigger problem with other pas haba b’kisnin.
Also, l’maaseh, most of the time it is a safek even with other pas haba b’kisnin because even if you eat 4 k’baitzas, if you are not full, it is still a safeik. And I still haven’t figured out what the definition of full is even though I tried looking into it and asking sheilahs about it.
Rav Bodner told me that Rav Aharon Kotler zatsal never ate a full danish because he considered it a safeik.
It’s also a safeik if you eat enough together with the pas habah b’kisnin to be considered a meal but the pas haba b’kisnin is less than 4 k’baitzas. I asked Rav Chaim Kanievsky about this and he said to say Mezonos, but I didn’t ask him if a yarei Shamayim would do this in the first place. I think that according to Rav Moshe Feinstein, you are not supposed to do that.
