Here's a few things I've learned from working at a hospital for 2 years now.
#1. When you press that button to make the nurse come in the room, ever wonder whats taking so long? No, they aren't busy, they just don't want to come in.
#2. When ordering food, always ask for disposable silverware. Keep in mind thousands of random strangers used that metal silverware before you did.
#3. Don't try to get up without the nurses knowing, an annoying as alarm goes off that sends everyone running to your room.
#4. You know how the nurses act very friendly when they are in your room? Well when they are in the hall talking to their coworkers they will be making fun of you.
#5. You know that person from food service you call to get your tray? They may sound nice, but you may be on speaker phone getting made fun of by 5 others in the room.
#6. When you get your meals, keep in mind this isn't a 5 star restaurant. Don't try complaining to the person delivering the tray or the people in the kitchen, I can assure you we don't give a stuff.
