A recollection: my wife and I were touring Alhambra (La Alhambra is what the spanish called it, but 'Al' is apparently the article in Arabic, so La Alhambra is a bit redundant) in Spain, and after walking around the whole thing were a bit tired. We walked out past some vending machines to the benches, and glanced at what was on offer: not only candy bars and fizzy drinks, but sandwiches, which we laughed at... who would eat a sandwich that had been sitting around under the Spanish sun all day; either it was chock full of potent chemicals, or it was already growing a disgusting range of nasties. Relaxing on the bench a few minutes later, we noticed a guy walk past, waving a few of the sandwiches, and exclaiming to his wife in a proud tone that he'd found something to eat. I guess the British deserve their reputation for not being picky eaters?
Now that is some awesome old technology. I can't believe the link to the audio file is broken! Thank god I visited TMRC to hear this thing in person before they took it to the museum.
If you can reduce McDonald's --or any fast food place's -- costs by X% and/or increase its throughput by Y% by an automated robotic means, you may have a golden business or start up opportunity.
