If all the shopping leaves you peckish, but you are a shy geek, or just too busy to stop off in a cafe, you can get a can of warm food from a vending machine.
This one was selling pasta, noodles, ramen soup and other meals in a tin; some chilled, others warmed and ready to eat as soon as they come out of the drawer below. These ones cost around £1.50 each. In other machines you can get curry noodles, fried chicken or chips.
