One of my customer's gave me flowers!
She had placed a large order of my custom hats, then when they came to her, the color was not quite a match for the team she was buying them for. So, after I sent her some fabric samples, I mad-rushed to remake her order (about 12 hours worth of cutting/sewing) and get them to her in time for a special event. The new hats got there just in time, and she was very happy with her purchase - and then she returned the original hats AND sent me flowers! Wasn't that too sweet?! :)
