Things not to say at a gas station

I stopped by 7-11 today. When I was in line, the woman in front of me bought a lottery ticket and told the cashier that if she won the lottery, the whole world would be happy. I interjected, saying that if she won, everybody that didn't win the lottery would be unhappy. She looked me in the eye and said that if she won the lottery, she'd share it with everyone, so then they would be happy. As she walked out of the gas station, I said, "Maybe you should give me your number, then." She may have interpreted that the wrong way.
