So there I was watching Pete Waterman presenting his Waterman on Railways program and they let the cat out of the bag on that huge British Rail con, the British Rail ham sandwich. This bloke who was a former British Rail chef demonstrated how it's done. When you look at the sandwich where it's been cut in half, you can see "two" slices of ham clearly visible and so you think, hhmm lovely and good value for your dosh and happily munch away on your ham feast. You've been conned. The ex B.R. chef showed you how. What they do is cut a slice of ham in half and place it in the middle of the sandwich so that when it's cut in half it looks like you have got two whole slices for your money. They save money because they only use 3 slices of ham for 2 sandwiches instead of 4 slices. The thieving bastards. I'm 55 and I've only just found out after all these years that I've been conned. Imagine how I feel! Anybody else come across any sharp catering tricks that we should keep our eyes open for?
