i go to the hospital just to eat at the cafeteria ... - who does the dishes in a 4 star restaurant

I'm not kidding.
When I don't even go to the hospital to see anyone but go to the restaurant all the time, I go to the hospital cafeteria!
Not only is the food cheap, but it is better than most restaurants, and the choice is always different.
Also, you can actually see what you ordered and only pay for what you want.
Another benefit is that you will meet a lot of nurses and healthcare staff.
Some of my local hospitals even thought I was a doctor or a medical equipment supervisor.
One day, when I was eating alone, I was thinking. . . .
Why do they call the doctor's business his "practice "?
Shouldn't he have all the "practices" he needs before he becomes a doctor? Cheers,ZacP. S.
Does anyone else like a hospital cafeteria?
