How do I tip my delivery partner?

Updated 

While you are not required to tip, your delivery partner would most certainly appreciate it if you did! You may leave your driver a tip on your credit card or debit card at checkout in the app. Your delivery partner gets 100% of your tip! Additionally, if you would like to increase your tip amount, or did not apply a tip, you’ll have the opportunity to do so after the order delivers in the app when leaving feedback.
