Walmart Phreaking by MaaDHaatR
Idea from RBCP from a PLA text about Fred Myers.

If you can't find the ext. for there Pa system in a 
WalMart try this. I found a better way to hack them... 
I did it today. Call Walmart have them patch you to 
Lawn and Gardens,(Or any deparment besides electrionics.)
Say your from some made up phone company, start asking 
them ?'s about there phones. Say there is some probs 
and your testing the line. When your done bullshiting 
them say "I have to do one more test, will you please
patch me to your PA system?" Then your in. Here is 
what I said to them
 
OP: Walmart, How may I help you?
MH: Patch me to Lawn and Gradens please..
OP: Ok one second...
LAG: Hello Lawn and Gardens. How may I help you?
MH: This is Joe Shmoe from Telco Systems United. 
We have been getting anomalys in your line. 
Have you had any strange phones calls?
LAG:No sir, I haven't been here for the last two days.
MH: Have you used the phone today?
LAG: Yes.
MH: Have you been able to call other lines from there?
LAG: Yes I have.
MH: Ok good. I got one more test to do, will 
you please patch me into your PA system?
LAG: Yes Sir...
From there I was in... Good Luck           MaaDHaatR
