If you're meeting strangers from the Internet, it's best to take precautions for your own safety: Meet in a public place, let someone know where you're going, etc. But you should also take care to ensure the safety of your personal belongings.
Redditor pointynipples69 shared the story of a friend who was far too trusting with his Tinder date:
"My buddy isn't the smartest man. He picked a chick up and drove to a motel. They were walking into the room and she says, 'Oh sh*t, I forgot my purse in the car do you mind if I go grab it?' He says, 'Yeah that's fine,' and tosses her the keys. 5 minutes later he walks outside wondering where she is and his car is gone."
