I had lunch at Jimmy John's today and sitting there reading all of the signs they have on the walls, I really wished I could take them with me and post them at work. Signs like these:
"If you want something to eat, make it yourself." Changed to something like "If you want a drink of water, pick up your glass and do it yourself" (if able to)
"If you need to do something when you need to do it, then someday, you will be able to do what you want when you want." (Wording may not be exact) This applies to the patients who refuse PT/OT and won't do anything for themselves.
"The customer is usually right" (not always right)
"There are three parts to an apology" I couldn't read the rest of the sign, but this could apply to patient, families, docs, nurses, etc.
Etiquette do's and dont's. Things like always say please and thank you, don't chew with your mouth open, etc.
And of course the sign that states "No shirt, no shoes, no service" Couldn't really think how that would apply to a hospital setting though.
