They have gotten a lot better but still need help. Wadi Natrun is a very remote, rural community and their culture is so different than ours that what we consider common sense may seem crazy to them. They also don't have what we would consider standard cleaning products, and they couldn't afford them even if they were available. We're still working with them and they'll continue to learn and grow. Their Mc Donalds does taste different than ours in some ways but not too many.
Camels spit just like humans do.
I have never been spit at by one before and hopefully never will. Ask your teacher how.
