I have marmite on toast for breakfast every single day. It's the best routine in the world, get off the tube, turn the wrong way for work out of the station, go into Benjy's and watch them make my toast on marmite (only 60p) while also watching them make all the other breakfasts, eat hot toast on the way to work. £3 a week on breakfast doesn't feel much of a luxury either, but it's so good having someone else make you breakfast each day.
