When I asked for more hot water for my tea, she scowled and then brought me new tea bag, new cup. She kept asking if I wanted more and said "no charge! No charge!"
As I was getting ready to go, she saw me take out a half empty bottle of sparkling water from my bag. She took it out of my hand, set it on the table, and said "no, wait." She brought me a glass of water with lemon and ice and said it was free for me and was I sure I didn't want anything else?
