As a client, you are in control of your tips and can make changes in two ways: Setting your default tip to 0% and entering "0" through the link in the SMS you receive after your scheduled appointment end-time has been reached.
To understand how to update your default tip percentage, just click here to view our Help Center article that will explain how to update this setting.
Or - you can always update via SMS after your appointment's scheduled end time. Here's an example of the text message you'll receive:
"Thanks for using StyleSeat! You'll be charged for appt + 20% tip. To edit tip within 24 hours: http://link.to.pay.tip.styleseat."
You'll just want to click the link, enter "0" for the tip, and you'll be good to go!
