Not just North Americans

Get a few kilometers away from El Centro and in the Colonias, you will see infrequent regular mask wearing but everyone carries them so that they can ride the combis. I frequent fereterias and building supply tiendas and many of them require customers to wear masks but not all require employees to.

I am pretty sure there is a general sense of virus fatigue couple with no one sees first hand what happens to the vulnerable when they get the virus.

Like I keep saying, I've been back and forth to Acapulco to one of its most crowded colonias, Colonia Renacimiento, several times recently in recent months as well as on the very day the contingencia sanitaria was declared, and I see most people in every town and village along the coast wearing facemasks. The problem isn't costeños in general, though the people who frequent bars are indeed careless by default. Pretty much everyone here knows numerous people who have died from the virus. Can't speak for folks from the inland cities or other places who don't actually know a lot of locals. There are always going to be necios and nacos who could care less, but the good thing about most folks from this region is most of them care enough to look out for each other.
