Supper here means dinner. Some places dinner means lunch. You're not going to get good results on an American forum with a bunch of niche meal options. You should have just had breakfast lunch and dinner in my opinion, I think you'd get much clearer results on if people prefer their morning, noon, or night time meals.
If I wanted to do a serious poll then yes I would have done Breakfast Lunch and Dinner but this is a semi serious poll so I included all eight meals eaten by Hobbits in the correct order they should be eaten.
