1. "In order to provide better service, we don't accept tips."
"We are convinced that quality service is necessary and no extra reward is needed."
3. "We are committed to providing you with a perfect health care experience, and tipping is not within our service scope."
4. "Here, all the service charges have been included in your consumption, and there is no need to pay extra."
5. "Our service personnel try their best to serve you, but they have been paid fairly and don't need to accept tips."
Such a slogan can clearly convey the position that health stores do not accept tips, let customers know, and avoid embarrassment and unnecessary trouble.
