Yellow pages may be retro, but they still work. Even when
the power is out.

1. So, wait for the next customer. Approach him and say: "I'll give you
$5.00 cash if you buy one of these for me."

2. The Yellow Pages DOES work if the power is out - but only half the time.
It doesn't work, for example, during the night.

But, of course, the internet doesn't work at all during a power outage.

This latter can be overcome by a portable generator and WiFi.
