Bits and Pieces, December, 1989, p. 2
Mamie Adams always went to a branch post office in her town because the postal employees there were friendly. She went there to buy stamps just before Christmas one year and the lines were particularly long. Someone pointed out that there was no need to wait on line because there was a stamp machine in the lobby.
"I know," said Mamie, &ls;but the machine won't ask me about my arthritis."
