📄 Example: Formal Apology Letter

Task: Apologize to your manager for losing your temper with guests at a water park.

Dear Ms Wainwright,

I would like to apologize for my behaviour, which led to a complaint from guests at the water park on Friday, 9th August. I realize it was wrong of me to swear at them, and they had every reason to complain about my conduct. Please accept my most sincere apologies.

Thank you for inviting me to share my experience of the incident. I helped the family, which consisted of two adults and two young children, to put on their life jackets and get in a canoe. Following park guidelines, I instructed them to keep the life jackets on at all times. However, when they were out on the lake, I saw the adults remove the life jackets of the young children in order to take their photo. I immediately asked them to replace them, but they refused. I admit that I lost my temper at this point and did not follow the park’s protocol to always be respectful towards guests.

I hope you understand that I reacted with the children’s safety in mind and that I was being vigilant in my duty as canoe supervisor. However, I recognize that I was in the wrong and should not have sworn at the guests.

I assure you that it will not happen again.

Yours sincerely,
Sam Partridge
