That's how I've felt about restaurants, where you're supposed to wear a mask when walking to your table but don't have to while sitting. Follow the science, supposedly... </sarcasm>
At one point, in Spain, they required you needed to stand up with a mask on, and then remove it in order to light a smoke(outside of course since it's the EU).
Depending on ventilation and table layout, it makes sense. When you walk to your table, you are contaminating the air in wider area while sitting. So it is logical but how big is the effect I do not know really.
