I had good service at lunch today. The waitress gave me a good menu suggestion, checked with me to see if everything was OK in a timely fashion, gave me my check in a timely fashion, and was all-around friendly. Good tip.
I had good service getting a haircut today. The stylist told me I had the "most nicest ears". I don't get that a lot. Good tip.
Stepping next door, I found Wii Remotes and Nunchuks on the shelves, with helpful, friendly servicepeople happy to chat with me as they facilitated my purchase. No tip, but I imagine they weren't expecting one.
Even the guy at the UPS store was happy and chatty and helpful. Again, no tip. I didn't steal his pen.
Celebrate the good times.
