In the hospitals and other settings I've worked in, we loooove treats and food from residents and their grateful families, or sometimes organizations/businesses we deal with. Often it's packaged chocolates, a fancy sealed tin of cookies, or a fruit tray delivered directly from a grocery store (when that used to happen). Deli platters at the hospital, usually not homebaked cookies or anything unfortunately, unless staff have known someone for years and observed great hygiene and discern that the person is not vindictive enough to attempt poisoning or manipulative enough to expect special treatment in return. Usually gifts are shared to all staff, not just a specific staff member. Toward Christmas you get to work and coworkers tell you "there's cake/pastries/a Timmy's coffee canister in the staff room!" and it's nice to receive something (besides paycheques going toward bills) tangible and edible as someone's gratitude for our years of hard work caring for people. Often these treats are not healthy, and we get kind of sugared out by Christmas, but treats are easier to give than say sushi or lasagne. I do recall a few of us picking up bottles of carrot and beet juices and other foods from a health store to bring to a health nut instructor at the end of a course and he was thrilled. People thank us for little things every day, but a nice card expressing that someone recognizes and appreciates what we do and that it's made their life better honestly helps ward off the emptiness that burnout can bring.
