I've been vegan for a little over a year now and I realized why that old joke is true for a couple reasons. For one, there are a lot of commitments that involve food with coworkers and friends, so of course the fact that you're vegan and accommodations will come up there. But it's also just kind of a lot of work looking into ingredients and the reasons for why ingredients are or aren't vegan. It just naturally becomes something you talk about with coworkers and loved ones.
