after the incident I am very upset

after the incident I am very upset with the lack of proper training in customer service your staff seem to exhibit. I am greatly discouraged from returning to patronize your store unless compelled.

Please choose your staff wisely to service your customers well for the long haul.

Yours sincerely,
