I had a boss give me a $5,000 bonus. THAT was a Christmas to remember.
I've gotten various gift cards and whatnot over the years, but for a truly personal gift, I had a boss who brought me back a beautiful scarf set from India and another boss who brought me a lovely necklace and earrings. (Their wives helped pick them out - no hanky panky going on LOL).
My current boss and I don't exchange gifts, though I might bring in a jar of homemade jam for each of the people I support this year - customized to what they have liked or sugar free if they are diabetic.
