On a side note, I went to the tire department at Costco a few days ago and just straight up could not understand the girl standing behind the plexiglass talking thru her mask. Pretty sure she couldn't hear me either and I ended up going somewhere else to buy tires. I understand the need for safety but if I cannot easily conduct a business transaction then I'm out.
