You and a friend shake hands and synchronize your wristwatches, your friend heads for a spaceship but you stay put on Earth, soon the two of you are moving at nearly light speed relative to each other. 3PM is the drawing for the big Powerball lottery, so at that time you use your FTL neutrino radio to send the following message to your friend "The winning numbers are 9-31-50-55-56-6. Please send this message right back to me". You look at your friend through your normal telescope and wait for him to receive your message, at 315PM by your watch you notice that your friend receives your message and looks at his wristwatch, but because of time dilation (which must be real even if Einstein is wrong) both of you will see the other's wristwatch as running slow. 

So at 315pm by your wristwatch you notice he gets your message and looks at his wristwatch, but what he reads is 215PM. So at 215PM by his wristwatch he gets your message and sends it right back to you with his FTL neutrino radio. He looks at you through his normal telescope and waits for you to receive the relayed message, at 230PM by your friend's wristwatch he notices that you receive the relayed message and you look at your wristwatch, but because of time dilation he notices that your wristwatch reads 130PM. That is 90 minutes before the lottery drawing, so at 130PM you spend a dollar and buy a ticket, you split the 245 million dollar jackpot with your friend and everybody lives happily ever after; except of course for the logicians, they are not happy at all.
