“The individual who arrived today, January 10, approximately at 4:45 PM, exhibited unacceptable behavior and demonstrated a lack of competence. By instructing individuals not to park in the parking lot adjacent to Garratt Gallahan Co and being aware that it was Saturday and the establishment was already closing, the individual’s actions were inappropriate and unprofessional.”

“Best water treatment company in the nation!”
