@kdfrawg funny story that happened this week.
I went to a Starbucks that was in a mall in the Atlanta area that was attached to a major department store that happens to be a Check Point customer. I ordered my typical 4 shots of espresso and I also ordered a venti ice water. They charged me $0.25 for the ice water (something a normal Starbucks doesn't do).
While waiting, I noticed they hadn't filled up the water yet and asked if they could instead fill up my aluminum container instead. They told me "had you asked for that to begin with, we wouldn't have charged you $0.25".
My response: They can have the $0.25 with my compliments.
