So every person will be getting their own slice of cake, but we also ordered a dessert table as we really enjoyed a showcase they gave us but unfortunately we could only afford 288 desserts in total (which cost A LOT), meaning each guest can only get 3 desserts out of the 8 different kinds of desserts being presented. Perhaps we should have only ordered a lot of the same thing but our dessert table vendor recommended we do different things so everyone will have stuff they like. How can we politely ask guests to not take too many desserts from the dessert table without being rude? Thank you for any suggestions/help
