If a man is a pig, he can get dirty with a fork and knife . It is not a matter of what is , but in principle in the culture of behavior of a particular person. I personally don't mind eating a sandwich or a bun at the table. If it is neat and does not interfere with others. There are worse people at the table. Which stinks, or frankly stinks. Who picks their nose or ears, cleans the dirt from under their nails , or bites them and spits out the remains, who laughs loudly and inappropriately, swears obscenities, or worse , threatens and scandalizes. So I think food is not the worst thing at the table.
