It's Americano which means they use shots of espresso and top it off with hot water so it wouldn't make a difference. Some of the really busy places have measured pours. In the case of paba they are just being annoying and stubborn.
I also can't get why people aren't on the environmental movement. Businesses are so wasteful because a customer complaint is painful. It's obvious most people just care about money, but it's sad and frustrating for the people who realize there is more to care about.
