So my FI and I went to select our cake, and afterwards we were discussing it with his ma... it was then that she made a special request... She wanted to know if they made gluten free cakes at the cake shop and if we would make the entire cake, which will serve 150 people, gluten free.... Apparently,my FI's distant older step brother's wife and children can't/won't eat anything that contains gluten...They are on these special diets that tell you what you can eat according to their blood type.... but regardless, am I being selfish for not wanting to make a gluten free cake? What is the polite way of handling this situation?
She said that sometimes they "fudge" their diet, so why can't they "fudge" it for the wedding cake?
