Several years after I graduated, I was working at a hospital and my neighbor, who said he had never set foot in a hospital since he was discharged as a newborn (no ER visits, never visited anybody, etc.) said "EWWWWW!" when I told him where I worked. I asked why he reacted that way, and in short, he thought that the whole inside of a hospital building looked like the TV show "ER", which was at the top of the ratings at the time.
I said, "No, the ER itself doesn't usually look like that either. It looks more like your doctor's office." I then told him that I didn't usually go onto the floors, and when I did, the patients were cleaned up and usually able to speak to me.
When I was in pre-pharmacy, I dated a man for a while whose drug use was probably a lot heavier than I realized at the time. Several times, he asked me, "If we're still together when you graduate, can you get drugs for me?"
I replied, "No, I am not going to get drugs for you. Are you kidding?" I'm not sure he was.
