[AFMUG] I thought this idea was foolproof

[Nate Burke]

When we help customers with their WIFI setup, we usually set the key to 
be their 10 digit phone number, makes it nice and easy for them to 
remember.

This usually works really well.
Enter the customer today, who called me on the number that the key was 
set to, but was unable to get it right, even when I was telling her the 
numbers.
