Why do some people blow their nose while sitting at a restaurant?

[X64]

usually older men pull out their snot rag and blow right at the table like nothing is wrong, and then proceed to wipe it several times before putting the snotty rag back in their pocket......!

maybe they think that nothing is wrong with it??
i know i find it HIGHLY disgusting. and rather annoying as well.

some people don't have any manners. it's as simple as that...,

Thank you for that tasteful description; would you prefer people to sit there and let snot run down their face instead of blowing their nose?

Would you rather they spewed into your food!?

I thought not.

Sometimes, mucus just builds up, and needs to be expelled.
It's not like your snot is sitting in your nose saying "I'm gonna start dripping. No, wait! We're in a restaurant. I'll wait until we leave before I start running."
