We have a water cooler and a fridge to make ICE. I installed a water filter.
I buy some bottled water, Gatorade powder and a box of trail mix snacks for the shop. I do not keep it stocked all the time with trail mix.
I try to take the group out to lunch a few times in the fall around the holidays, and I try to get one or two of them to lunch one on one from time to time.
