I witnessed for myself on Saturday the indoor part of an amusement park where - despite very obvious signs at the entrances stating masks were mandatory - comfortably under 10% complied. And it was very busy.
Before anyone asks we were in the cafe section for coffee and cake so didn’t have to mask up, and spent the rest of the time outside.
In relation to aviation the point I’m making is the number of people unwilling to wear masks once they feel they can get away with it will grow and grow.
