Taco Bell, Jesus like

I was going through the drive through window at my local Taco Bell earlier today. I was on the phone with my dad, so I was ordering at the window and talking at the same time (the reason multi-tasking was invented). When I came around to the window, I realized I had left my wallet at home. Sadly, I could not scrape together the 96¢ needed to pay for my chicken burrito. At that moment, I needed from the drive-through guy what we all need from God; grace. I apoligized for not having my money and I asked him to cancel my order. He instead said that this one was on him and he allowed me to pass through and I drove to thes second window and picked up my burrito. After this, I went home and got my wallet, and 96¢ exact change. I returned to that Taco Bell and I paid off my burrito debt, even though I don't think they were expecting me to. What did I learn from this experience? I think my faith has been restored in humanity or something?
