Grocery Store Manager Paid for My Order — Stranger Acts of Abundance Keep Happening

Back to back positive experiences. Yesterday at a doughnut shop they said cash only and I only had a card — when I pulled up to the window, the guy said just give me a dollar, and threw in an extra donut for free. Today I went to the store for a 24pk of water and my card had insufficient funds. I walked out. But one of the managers chased me to my car and told me to come back inside — he went ahead and paid for my groceries. I was so shocked.
