I go to a provider regularly and they continue to initiate extra services without prompting and you continue to leave a regular size tip, not a tip that covers them going above and beyond what was paid for. Now, that would indicate to me that the provider doesn’t mind going above and beyond bc they are the one who prompts it every time. So it really just depends for me on how things go from session to session.
Now if they initiate it the first time and don’t in the future, that would be a good sign they weren’t happy with the tip. But if I’m a regular and they keep starting it, I’m going to assume they don’t feel the need for a tip that matches what they’re offering.
