I have mentioned I drive a school bus. Students are 4th through 6th grade. About 10% thank me when getting off the bus both mornings and evenings. This may be a reflection of my greeting each of them with a good morning, good night or just a hello as they enter or exit the bus. I think it also reflects on the parents teaching their children to be polite. As a child I was always taught to say please and thank you to everyone and still do. I also greet people in public with a good morning, good afternoon, or good day. This includes store workers, servers, and anyone whom I may have an in person contact. I think being polite, especially these days, is very important. I think it makes people feel good, even if it is just yourself. How about you?
