Encountered a gentleman who works for D K Security...

Encountered a gentleman who works for D K Security at the Secretary of State office in Kalamazoo on Stadium Dr. While I understand that office was handling the work of another office due to an emergency, there was no reason for him to be rude. When people would walk up to the area to get checked in (which was outside in the sun). He would yellbat then, "do you have an appointment" and then very sternly would say "get up here" to ask questions about their appointment. Everyone was asked to repeatedly to state their name, both first and last very loudly. (HIPPA)
A simple please and thank you goes a long way with customer service.
