Grocery gift cards along with a personal note would be welcomed. Gift cards that people won’t use, aren’t very helpful, but ones for the local grocery store or Walmart if there is one in town is a good choice. Everyone buys groceries, and Walmart sells such a variety of things that pretty much anyone can find something they want whether it’s food, electronics or clothes.

As someone else mentioned, give separate gifts/cards for the night shift. Most of the time they miss out on gifts and food all together because they are gone before they ever make it into the building for their shift.
