I need help figuring out how to make them stop

I stayed at a homeless shelter and an employee there was named 'Royce'. A business nearby had a sign posted saying, "Come roll with us" like rolls royce.

I then had a veteran case manager who said the word 'Royce' when she was helping me apply for VA disability.

Now I am at the hospital with my mother and one of the nurses is pretending his name is Royce. They have 'Royce ' written on a marker board above the nurse's station.

I'm confused as to why these people would want to harass me like this. I don't know how to make them stop. Your advice will be greatly appreciated.
