Jack is a Vietnamese.One day,he sold a piece of replica ROLEX watch to an American,John.
After John received the watch,he found it didn't work and he immediately wrote an Email to Jack,whcih read "Hi,there.I have received the watch.You said it is perfect in quality,but it didn't work here.Why?"
Jack replied soon"Dear John,I am so sorry to hear that.Also please be patient,because of time difference,it may work 1 day later."
