Time Zoned Way Out

(I am on the phone.)

Me: “I sent the instructions to you in an email about half an hour ago; have you received it?”

Customer: “No, but I am in the next time zone, so I will check in another half an hour, at the time you sent it.”

Me: “If you would please check your junk mail or spam folder, just to be sure?”

Customer: “Oh, hey! Look at that! It’s already here!”

Me: “Computers are amazing, aren’t they?”

Customer: “Wow! They sure are! How did it know?! Oh, well, I have it now. I’m gonna open it before it realizes that it sent it early and deletes it.”

Me: “Sounds great.”
