We just did household accounts.
Every time I buy canned peaches, with no sugar added, I get caught noting the "NSA Slcd Pchs" on the tape.
I blame a friend of mine who works for them.
(NSA, not the grocery store.)
Hmmm....sounds like a classic covert channel attack. I recommend you shred and burn the tape immediately. Wait, are those helicopters I hear. Gotta go!
