They finally got the part installed and I hit the road at 4PM , with about a 6-hour drive ahead of me . Susan and the girls had arrived hours before and were shopping for house stuff . About four hours into my drive Susan called to say that the van had a flat , and AAA was flummoxed because we changed our membership to the Texas " club " but Susan 's mobile phone still had an Atlanta area code .

Question: Why were they so confused about the area code change ?
Answer: The membership was made for Texas but the phone number was from Georgia .The tire was located in Atlanta when the people were in Texas .They did n't know where they should dispatch and fix the tire .They were n't sure if it was the real people calling .
