  If you mean people who cover their nose with their arm/sleeve/tissue/etc., then sure. People who don't are unhygienic, disrespectful, and impolite.  
  Saying "bless you" isn't exactly polite to everyone. It's  quasireligious, and these days, that's not gonna be taken kindly among a lot of demographics. >
  
  I honestly fail to see how it's considered impolite to not "bless" someone after a normal everyday bodily function. It seems obvious that it started from some religious superstition and I'm neither religious nor superstitious. It's truly a confusing thing to me. >
  
  Saying bless you is a weird ongoing tradition. 
  I believe we started saying it when it was an indication that you had the plague and would shortly die. “May God bless you” would be polite. 
  Nowadays sneezing is not an indication that your dying, but of all the bodily excretions, this is the main one that spreads disease. 
  If I burp or fart, no harm to you but politeness dictates I have to ask to be excused. If I yawn, no harm to you but I have to cover my mouth. 
  If I sneeze and subject you to a barrage of bacteria and virus particles, you have to bless me?! I should be saying excuse me when I sneeze. 
  I could argue that a burp, fart, yawn, all normal human biological functions should go as unremarked as tummy rumbles. >
  
  My wife gets annoyed when people say, "bless you" because then she has to say, "thank you," which she finds annoying for some reason.
