I have one. I was at my daughter's wedding two weeks ago. As a background to the story, they are not vegans, but many of their friends are, so they offered both vegetarian and meat dishes at the wedding.
Finally, the caterers brought out the coffee urn, and set some 1/2 and 1/2 in ice nearby. That was all.
I asked the caterer, who was standing in front of a vat of BEEF TENDERLOIN MARSALA, where the sugar was. This was his response:
"The couple is vegan. So we didn't bring sugar."
I proceeded to tell him that sugar was in no way a meat product, to which he replied again that they were vegan. Ughhhhh.
The man behind the bar at the venue had some sugar. And a good laugh.
