Going to Alajuela the other day I snapped a cellphone photo of the mask-requirement sign and the markers on the sidewalk to make sure we stand in line 1.8 meters apart (the same as 6 feet), but failed to snap the hand-washing station you must use before going in bus or in the little coffee shop.
Mask-wearing is required in public by national law now and almost everyone wears a mask. I only occasionally see a man or young person cheating but they usually have a mask in their hand or in their pocket.
¡Pura Vida!
