Britain's answer to street food. No road in this country is complete without a few of these parked up in lay-by's, offering sausage, bacon and egg sandwiches or the odd burger at £3 a go including a mug of tea. Usually the meat is cheap catering grade stuff; best not inquire on its provenance. However, sometimes it really hits the mark - cheap sausages and a runny egg between two slices of 'plastic' white sliced bread and a mug of steaming hot tea by the side of a busy road just seems to work. Do you use them, or do you even have them in your part of the world?
