Were they stay-overs or check-outs? Isn't a buffet all you want? They figured it is also WHEN you want.
I make mini-muffins so I can send them off with a box of muffins as a "care package". A half recipe makes almost 2 dozen minis. Gives enough to do breakfast for up to 4 people (remember I only have 3 rooms) and put at least 6 in a pastry box for the road. Takes care of the "want extra out of you" and makes a feel good at the same time - they did not have to ask. Last week I had 2 sets of guests ask if I had containers (I serve family-style) - and they emptied every dish - there went MY breakfast of leftovers.
