He had suggested installing a window in the lobby door. Sometimes people leaving the lobby pushed the door open hard. A window would allow people leaving to see people entering. A window would help prevent people leaving from knocking down people entering. Two days later, the door had a new window. "See what quick service we gave you?" she said.
