Yes friends!
After the program, I kept my "lapel badge" on.
So while filling up my car with fuel, the attendant asked me about it. I was able to share some great points about the wonderful program my wife and I had just enjoyed in Sydney all weekend!

Truly, it seems like "God" had blessed our efforts, and provided an opportunity for a fine witness! Oh, and the attendant showed such interest, that him, his family and twelve relatives all accepted literature, and expressed that what we were saying "must be the truth" and are on their way to baptism......
OK, last bit was a force of habit after a lifetime of witness "experiences"
