One thing that got under my skin when I was doing ambassador work at the hospital was trying to have small talk with patients while taking them to whatever floor they needed to be on.
It's hard to say, "how are you," "are you having a good day?" and "have a nice day," because, you know, your in a hospital and the answer to "how are you" is "not very good".....Someone should write a book on things you can say to a patient that won't remind them they are not doing well. I usually talked about weather, but that got old after 15 patients in a row. I loved doing the work though and recommend anyone interested in healthcare to do some volunteer work at the local hospital.
