No Spitting or Blowing Your Nose
If you have the sniffles while visiting Cuba, don’t even think about whipping out a tissue or handkerchief and blowing your nose in public. You have to take care of your nose-blowing business in the bathroom or hotel room—anywhere that the public can’t see you.
The same thing goes for spitting. If something’s caught in your throat, go to a bathroom and hock up your loogie where you won’t disgust passersby. It can be inconvenient, but it’s better than being alienated by everyone around you who thinks that you’re some gross nose-blowing, loogie-hocking freak. You can wait a couple of hours before clearing your sinuses, can’t you?
