Drive person was impatient. I had waited four cars deep to give my order. I had a birthday coupon for a shake. Unfortunately my phone froze. Caused a delay. She said you know I have other cars waiting. I knew that, I waited my turn. So I said nevermind I will pay for it. She said okay. Gave me my order without the shake! When I questioned her she stated I gave you the tea and food. I said what about the shake? What? I told you I would pay for it. Um, oh? What size? I can’t believe it! Really? I drove off. Thanks for the great start of my birthday!!!
