When it comes to showing your appreciation for great service, there are a number of ways to do so without having to tip. One way is to simply say thank you and mean it. A sincere thank you can go a long way in showing your appreciation. Another way is to write a positive review or testimonial about the person or business providing the great service. This not only shows your appreciation, but can also help others who may be looking for similar services. And lastly, if you have the means, you could always make a donation to a charity of the person or business’s choice in their name. While tipping is always appreciated, sometimes just expressing your gratitude in one of these other ways can mean even more.
