My husband has worked in construction for almost 40 years, so almost always had a packed lunch. I can't tell you how many times I forgot to put a spoon or a fork in his lunches. He usually takes a thermos with leftovers for his lunches. He has eaten with a carved shingle many times. He actually got pretty good at making them, carved out with a drywall knife.
The problem is solved now. He packs his own lunches and NEVER forgets the fork or spoon.
