Lunch consists of an Egg & Mayonnaise Sandwich (which is surprisingly like what we Americans would call an Egg Salad Sandwich), a bag of crisps (potato chips), and a bottle of water, which at £1.10 seems pretty overpriced. In general, I'm pretty sure most of the bottled water here in London and in Ireland is sold to tourists, since the local water isn't bad. I end up buying it just because the bottles are convenient to carry around. If I were even smarter, I wouldn't throw the bottle away, but would just refill it whenever we came upon a bubbler.
