We stay in hotels in Switzerland that offer bed AND breakfast. Breakfast is paid for and is not a courtesy offer. We have noticed a wide range of consumption habits at breakfast from mouse like to trencherman. Average quantity consumed must be well known by hoteliers and I have always felt that room pricing allows for the average observed.
I have seen several times food taken away from the breakfast room, most often by those who have eaten little at the table.
Perhaps habit and practice varies between countries and nations.
