OK. I normally try not to buy water. It's a pet-peeve. I don't like to buy water and I don't like to pay to park; both should be a God-given right!! However, I was traveling Friday through the San Francisco airport and wanted some water. More so, I wanted the bottle to keep with me throughout the day. (I'm trying to stay hydrated:) I went to one of the coffee shops and when the cashier rang up the bottle, I almost had a stroke! They wanted $4.15 for 1-liter of water. I seriously did a double take and asked him if he was serious. When he didn't even bat an eyelash, I quickly put it back and said no thanks. I got my exercise walking back and forth to the water fountain.
Lesson of this story: ALWAYS carry my refillable water bottle!
