I think this may have strayed too far from its origins as a poverty food. White bread, butter, cucumber and mayonnaise (if you're fancy) paired with some weak tea drowned in milk is a perfect way to save money so you can afford to have a TV license to watch England lose at football or splurge on Wensleydale Cheese to eat with your Christmas fruit cake and Christmas goose or go to Ibiza and get horribly sunburnt while complaining that the Spanish people are speaking Castellano.

Plus it helps keep you thin so you can fit in chimneys to sweep.
