I've never yet been on a dig where there wasn't at least one vegetarian or vegan. And there's always been a tedious ass-hat trying to wind them up - and that really needs to bite the dust. Volunteers and staff members on excavations are increasingly requesting vegetarian food, or vegan food, or - for medical reasons - food that is gluten-free, or lactose-free, or low in sugar. And good on them. People who choose to try to care for the planet in this way and look after their own health should be welcomed in my book, not excluded or derided.
