At approximately 12:55 p.m. after church service, I went to the loction noted above and ordered a large caramel malt with no milk added. The worker completed the order and then informed the male manager that she had done so and discribed the order. Immediately, the manager became upset and expressed himself in an angry tone and instructed the worker to discard the malt and start over making the new one with milk. As the worker explained once more that I did not want milk, the manager stated, "I don't care, make it with milk". I observed this discussion and it did not conclude until I tapped on the window, advised that I could here the discussion, and requested that the order be canceled and my money be returned. I did not understand the manager's level of upset. I am certain the the amount of icecream served fot the malt is the same with or without milk. It was distrubing to observe his behavior and tone.
