"Should I tip my nurse?"
"Should I tip my nurse?"
Why should we be the only ones not to profit from it ("pay-for-care") 
The whole sub is just awful. They advocate for calling patients "clients" too.
The clients thing was in nursing school too, the older guard thought "patient" implied too much power dynamics over the person in question. I didn't get that literally at all, none of my classmates did, none of my coworkers do - unless you're over 55 and in academia and haven't been a floor nurse in over a decade. The profs insisted client was a better term because it leveled the implied hierarchy - but all of us thought it was gross because it's a business term.
Oh yeah and people give nurses stuff all the time. We've got chocolate, cards, I got a t shirt once. It's all lovely and appreciated. It is unethical to accept gifts over a certain dollar amount, I think $100. We usually redirect them to donate to the hospital foundation, or return precious items to family (like jewelry). Its normal human nature to want to show appreciation to people who cared for you and some people feel they can only show it by giving gifts.
thank you card and a box of chocolates for the nursing team is also pretty common here
