I work construction. Today I got on a new job at an existing hospital, but couldn't find my way around...

Wearing ragged overalls, and smelling of old pennies, I politely asked a nurse if she had seen the company I was here to meet. She informed me they were set up on the roof. We were both on the ground floor at the time and upon seeing the disdain in my eyes she offered to show me to the access area. She was a cute little blonde thing, and I accepted the offer.
She takes me to the elevator and we ride up to the 5th floor. She's yapping about something I wasn't fully paying attention to as I'm trailing her down the corridor. I glance left and right through the oblong windows in the doors to the patients rooms. Not much to see.
As we near the end of the end of hall, she turns back to face me and spots me staring straight into a patients room, my mouth ajar.
"That man is in there jerking off!"
It was fairly violent too. She informed me he had a rare condition that would result in cardiac arrest unless he rubbed one out every couple hours. I told her to keep me away from that guy.
We climbed up one more flight of stairs and turned down another corridor with rooms lining either side.
"It's just ahead sir," she said, " just through the double doors at the end."
I was still a shook up about the scene I'd just witnessed one level below, so she took me the rest of the way.
Sure enough I see another man, a FULLY grown man, yanking on his thing. HARD.
"What the hell is going on around here?" I asked her.
"That man has the same issue as the fellow downstairs. Isn't that interesting?" She exclaimed.
'Hardly,' I thought. We kept walking.
Just then, to no avail, I look into another room, unable to keep my prying eyes away, and there it was. A nurse in her little whit outfit, hair tied up in a bun, blowing this mans cock! Right there in the patients room!
I asked the nurse I was with, "So what's the deal with this guy??"
She looked over her shoulder slowly, "Same disease, better health coverage."
