Things seem to get watered down rather than smaller, if that makes any sense. For example, the pizza slice is the same size, just with skimpier toppings. Or they replace quality ingredients with worse ones.

I'm not a regular soft drink consumer by US standards. When I like one, I usually like an 8oz bottle. Why does an 8 oz serving cost a lot more than a 12oz serving? And to really change directions, why can't we refill bottles?
