3☆ on my birthday. Ruined my day.

I wasn't going to work today. But decided to take a new to me customer who lives 4 blocks from me. Easy delivery! Everything went smoothly. The customer offered to buy me a snack. I chose a chocolate chip Muffin because I didn't want to get anything too pricey. I asked her how she knew it was my birthday! We had a little laugh that she just "felt it." I took my time selecting the best produce. Which included sending her pictures of the cherries she wanted because she was particular about the color.
It was essentially a perfect shop. She came out when I was delivering and she was very sweet. She requested me as a preferred. I thought, "yay!" A 3☆ just showed up, no growth opportunities. Was it her? I think it was. Why???? Some people 🙄
