I’m vegan and I work at a small office where it is common for people to bring in food to share. Sometimes I get lucky and receive consideration from the food-bringer, but in at least as many cases, I find myself neglected and left out. I don't expect to receive consideration from every person every time, but there is one case that feels particularly egregious to me and I'm not sure how to react to it.
There is a donut shop a few blocks from our office that offers most of their flavours in both vegan and non-vegan varieties. When I bring back donuts from the shop, I always make sure the whole order is vegan (of course) and there are no problems because the food is suitable for everyone. But when other people pick up donuts from the same shop, they frequently either forget to get vegan donuts, or just get everything in one box without labels so it's impossible to tell which ones are vegan.
It's not just me, either; there's at least one other vegan in this office. After eight months of working here I'm fairly sure that all of my coworkers are now aware that I am vegan, either through direct conversation or other indirect cues. I know that people aren't overwhelmed by trying to accomodate many dietary needs because there are no people in our office with severe allergies.
Edit: I live a vegan lifestyle because I believe we should avoid doing harm to animals. When I purchase or make food to share in the office, I would never bring in something non-vegan because I believe that would be unethical.
What can I do to increase my chances of being included? Would it be unreasonable to ask that only vegan donuts are included in future orders?
