Dear {Recipient},

I'm sorry I didn't leave you a tip after dining at {name of restaurant} this past {day of the week}.

Please know that it was a complete oversight on my part and not a reflection of your service at all.

Enclosed is a check for {dollar amount} to make it up to you. I have also written a letter to your manager to let {him/her} know about your excellent work ethic.

Dear [Name],

I am writing to apologize for my uselessness. I know I have not been the most productive or helpful person lately, and I would like to take a moment to explain why and apologize for my behavior.

First of all, I want to let you know that I am truly sorry for not being able to contribute as much as I should have. I know that it is my responsibility to be a productive member of the team, and I have not been living up to that responsibility.

The truth is, I have been struggling with my mental health lately. I have been feeling overwhelmed and anxious, and it has been difficult for me to focus on my work. I know that this is not an excuse for my lack of productivity, but I wanted to explain why I have been so unhelpful lately.

I understand that this is not an acceptable way to behave, and I want to assure you that I am taking steps to improve my mental health. I am seeing a therapist and taking medication to help me manage my anxiety and stress. I have also been trying to make lifestyle changes to help me stay focused and productive.

I understand that I have let you and the team down, and I am deeply sorry. I am committed to getting better and becoming a more productive member of the team. I will do my best to make up for my uselessness and to be a more helpful member of the team.

Thank you for taking the time to read this letter. I appreciate your understanding and patience.

Sincerely,
[Your Name]
