[rolls down driver's side window to grab parking garage ticket]

Shit. Should I be wearing a mask? How much air exhaled by the driver before me am I inhaling right now?

[orders at a McDonald's drive-through]

Shit. Should I have worn a mask?

All the cars ahead of me have their driver's side windows down. Should I roll up mine before reaching the pick-up window?

[pulls over at the behest of a police officer]

Shit. He's not wearing a mask. What if I refuse to roll down my driver's side window? Can I ask him to stand six feet away?
