I've heard "Second Breakfast" is actually a thing with farmers, i.e. they get up super early (say 4am) to feed the livestock or do some other such thing (cow milking?) and they have a lightish breakfast - a cuppa, some cereal or maybe toast. Then later on, say 730am-8am, once these tasks are done and dusted, they head back to the farmhouse where they have a more hearty affair - sausages, bacon, eggs.
