Dear Manager,

The purpose of this letter is to bring to your attention an incident that occurred during my recent visit to your bank. While I was conducting business at the bank, an intoxicated man entered and began misbehaving with the staff and customers. This circumstance was extremely upsetting and made everyone feel unsafe.

I was shocked to discover that there were no security measures in place to prevent such incidents. No security personnel or guards were present to handle the situation. If the man had inflicted physical harm on anyone, the situation would have been much worse.

As a frequent customer of your bank, I am extremely concerned about the security of the employees and customers. I believe that it is the bank's responsibility to provide a safe and secure environment for all customers and visitors.

I urge you to take the necessary steps to enhance the bank's security measures. This will not only make the staff and customers feel safer, but it will also enhance the bank's reputation. I hope you will take this issue seriously and address it without delay.

Thank you for your consideration of this issue.

Sincerely,

ABC
