I had someone in the produce section the other day trying to get my attention, but since I had airpods in specifically to zone out the "ma'am! ma'am!" walking in the front door, I couldn't hear him. I assumed he was an employee trying to tell me to put a mask on. Turns out it was another unmasked person & he just wanted to give me a high five. Conversely, I had a fellow customer in the meat section the other day ask me where my mask was. I told him I didn't wear one, but thanks for his concern.
