Something along this line happened to me several years ago. I belonged to a girls group that elects officers every 6 months. When the head of the organization time is up, they would receive publicly a bouquet of flowers, usually roses. Both my mother and I made sure that the adults in charge knew of my allergy to roses, but the main adult purchased them anyway, with a snide comment to my mother, "they WILL be roses!" When it came time for me to go forward with bouquet on arm, I left them at the back. When someone brought the bouquet forward and put them in front of me, I took them, handed them off to the local dignitary at my side and said, "Would you please take these away, I'm allergic." This happened in front of 200+ people. When the main adult tried to say she didn't know, my mother and the other adults reminded her that she had been told.
