I used Lyft 3 times while in Las Vegas and was pleased at the quick pickup & inexpensive price. The app is cool because it tells you exactly where the lyft car is located. Plus paying for the ride is easy because it comes off your credit card so no need to have cash in hand. All the lyft cars were new and drivers were nice. Lyft gave me a $5.00 discount every time i used the car service.
Once the ride is done you will recieve a message from lyft to pay for ride with the credit card you provided and at that time you add the tip. Super easy and safe.
I always tip at least $5 to $10 depending on distance. Or at least 30 percent. I feel the more you tip and take care of others " God sends you Blessings".
