BLOWING YOUR NOSE AT THE DINNER TABLE!! ETIQUETTE? STUPIDITY or DISGUSTING?

I absolutely cannot stand going to a restaurant, sitting at the dinner table and someone gets a tissue or hanky and blows! What is wrong with properly excusing yourself from the table to blow your nose? How about if Snot just falls in your plate of food? What if you have hanging objects? Then you pick up your food and start eating? This is just absolutely disgusting.. & People that do this need to be kicked out of the Restaurant. There are places to blow your nose.. It's not at the table... "
