If I was in an enclosed area which was over crowded then I will probably put one on. I suspect I will keep carrying them around in my bag incase they are needed.
If a shop/restaurant/venue requests they are worn I will wear one if going in there. I wouldn't not put one on just to prove a point, for example - masks really don't bother me that much tbh.
I suspect they will continue to be needed for planes and airports anyway.
I don't wear one that much now anyway - I use online supermarkets and shops (I am not a big fan of shopping anyway), and we don't wear them in lower primary schools. If going out I wear them for the quick walk to the table and remove it when sat.
