Wonder if the hospital admin. failed to make the VP (or his staff) aware prior to or upon arrival deliberately. Stranger things have happened. IMO its incumbent upon the hospital to make sure everyone is aware of their policies.
Yes, there is no reason the hospital would not have provided him with a mask when he arrived.
I have been to a hospital 4 times in the past couple weeks, and there are signs EVERYWHERE that you must put on a mask when you walk in the door.
