I went to a Toby Carvery the other day. I had two types of meat, a Yorkshire pudding, veg and gravy. I had a good sized portion, ate it all and didn't feel the need to go up again. I'm quite smug that I know how much to put on my plate without wasting it.
However, I could see the gravy/sauce table from where I was sitting and saw a few very overweight young people, late teens/early 20's with 3 - yes 3 Yorkshire puddings on their plates, a mound of veg and ladling on bucketfuls of gravy.
Surely this is not normal and they were just greedy.
