Guy comes into office, Mary slides open her window.
Mary: "Hi, you have a 1:00 appointment? Okay. Can I make a copy of your insurance card? Thank you... Do you have a mask?"
Mr. Beijerinck: "No. I don't need one."
Mary: "Dr. Grumpy asks that all patients wear them. Let me give you one."
Mr. Beijerinck: "Little lady, the pandemic is over, if there ever was one. I ain't wearing a mask."
Mary: "Sir, because of the nature of his field, Dr. Grumpy sees a lot of patients on medications that suppress their immune systems, so for their protection we ask that everyone wear a mask when they go back to see him. Here's one you can wear during your visit."
Mr Beijerinck: "You want me to wear this?"
Mary: "Yes, just while you're here, please."
Mr. Beijerinck: "Okay, here."
He tears the mask into little pieces, tosses them through the window onto Mary's desk.
Mr. Beijerinck: "That's what I think of your bullshit rules. Now, honey, just go tell the doctor that I'm here for my appointment."
Mary: "Thank you for letting me know. Here's your insurance card back, I haven't copied it. I'll let the doctor know that I cancelled your appointment. Have a nice day."
Mary closes her window, pretends to answer her phone, and ignores him until he leaves.
