Hardee's Restaurants

On July 4th I was driving in my car and had a sudden immediate urge to urinate. I'm 85 and have a prostate problem that is controlled by medication,
however sometime but rarely I still have a sudden, unexpected urge to urinate.
As I was close two a dairy Queen I quickly stopped to use their rest room but the store was locked tight. Just a short distance was a Hardee's so I rushed there. Fortunately the door was unlocked, so I entered and was just rounding to corner headed toward the rest room and someone very loudly called "Hey" two or three times. I look up to see a fat black woman hollering "Hey" at me.
She said very loudly and aggressively, "you can't be in here with out a mask!"
I replied "I really need to use the rest room" She very loudly repeated her pronouncement that 'You can't be in here with out a mask"I said"I'm sorry but I need to go badly"and I entered the rest room. After I few minutes I had finished my"business"and she began banging very loudly on the door. Then she stuck her head in the room and yelled,"Are you done, yet"?
I said that I was and finished washing my hands and left the restaurant.
After exiting I did see it posted on the door that masks were required. Unfortunately my need was such at the time that I couldn't stop to look at all of the notices on the door.
Just want you to know that I am used to being addressed as Mister or Sir, I resent be addressed with"Hey, "Hey" and your employee didn't need to harass me while I was in the rest room.
Just as a side note, Did not see any one else in the restaurant, but didn't have a lot of time to look. Also, I do not have COVID19, I do not know anyone who has COVID19, and I do not know anyone who knows anyone who has COVID 19.
I'm not looking for anything from Hardee's except a little respect!
