He has previously put out a box of gloves and disposable masks. But, people put the masks on and pull them down, or think it's a cute joke, etc. No. It's not a joke. Last year he put a note that anyone sick was not to enter. Either phone or e-mail. One guy came in laughing about the note and coughing. My husband picked up his jacket and walked out. Many years ago he almost died from a flu. Just a normal flu. It weakened his lungs. Last year he ended up in the hospital for a week. Paramedics weren't sure he was going to actually make it to the hospital. He didn't have the flu, though the symptoms seemed like it.
So, his office is his "safe zone" at work.
