W/R to people hanging around trying to spot credit card numbers:

There are probably loitering laws on the books (don't know the juris-
dictions involved), but further discussion of this is beyond the scope
of telecom.

As a reminder: If the phone is rotary (or pushbutton pulse), a credit-
card call requires you to read the card number to the operator, and a
common source of fraud was/is the overhearing of such card numbers.
If the phone is touchtone, you usually have the self-service credit
card number entry available, and the problem then becomes that of
someone watching over your shoulder(?).  Corrections or more details,
anyone?
