Go to Menu > Settings, then scroll down to the 'Tips' section.
Has Tips': You can disable this option if you do not want to offer tips for a particular menu.
'Allow a customer to choose their own tip amount': Enabling this option allows customers to enter a custom tip amount in a free text field.
'Fixed Tipping Options': Here, you can set up three standard tip options. You can choose to display either a fixed amount or a percentage-based tip on the total basket value.
