You can now tip your Ola driver. The Indian ride-hailing giant said on Tuesday that it has rolled out this feature to its users in India, Australia, New Zealand, and the United Kingdom — all the nations where it currently operates.

Ola said riders in each market will see a range of denominations they can pick as the amount they wish to tip digitally. It plans to allow riders to pay a custom amount of their choice in a few weeks, a spokesperson told TechCrunch.
