I have listened to music way too loud for a way too long on my phone. Now I cannot understand when people are saying to me when there is background noise and they have on a thick cloth mask. Add in plexi-glass and I'm done. I just nod and grin. It's me, not you. Thank you for wearing a mask (for real) for all workers that have to wear a mask all day, you are awesome. Sorry, I can't understand what you are saying. I am not trying to add frustration to your day.
