Write a formal apology letter to a patron from the owner of a restaurant. It was a customer service issue and be sure to offer some type of compensation. Thanks.
Dear Patron,

I am writing to formally apologize to you for the poor customer service you received while dining at my establishment. I would also like to thank you for bringing the issue to my attention. As the owner, I feel it is my responsibility that all patrons are treated with respect and our servers should always be polite and professional. I assure you that the responsible parties have been dealt with and the issues you experienced should no longer be a problem.

As an apology and a thank you for dining with us, I would like to offer you coupons for two free entrees on your next visit. Please feel free to reach out to me directly if you have any further questions or experience any other issues. Your feedback is extremely important as I wish to constantly improve the experiences for all of our diners.

Sincerely,
Restaurant Owner
