Number please

(1978 September 29)

I have been very busy lately answering the phone for the vacancy ad of house next door (Lulu's). Have key and show it by appointment. ... This has been an interesting experience for me, meeting the public, so to speak. One caller, a foundry worker, was so sleepy when he called he could hardly speak. When I asked his phone number, there was a long silence. Then he said he couldn't find it. -- Then he said, "Six thousand seven hundred and forty three."
