I had lost a spring bar while changing the bracelet of a JLC Master Series watch. I quickly explained this to her, sheepishly as I was embarassed. She asked me to give her the bracelet and the remaining spring bar. I complied. She went to the back and found an identical one. And she gave me an extra one as well. All gratis. In a little plastic locking bag. I thanked her. And I've already forgotten her name. I appreciated her help very much!
