Back in the old days, you'd pick up your date by driving over to their home, and ringing the doorbell. These days, you send someone you don't know to do it.
Tinder has partnered with Lyft to add a feature where you can buy a Lyft for your date within the app. And it isn't just a courtesy, it's also a bit of a safety feature.
The person buying the ride doesn't get any details about the date's address, but they can set the time and value of the credit they want to purchase. Then, the recipient gets a link through a text or email.
