A teacher in HS gave me the advice "At work, be good to the first person you see in the morning and the last person you see at night. That's usually the front office folks and the janitors. They can make your life better, or hell, and it's your choice."
I really try to be super nice to nurses, techs etc I work with mostly because why not, makes it better for everyone but also has the added benefits of they help me out, point out when I may have erred, invite to eat at potlucks, and when I have less common requests are happy to help
