Problem with getting correct data out of buffer reading from channel

[RedGrittyBrick]

No more so than saying "machine" in "ATM machine". You have to say "ATM
machine" so you know you aren't speaking of the "ATM card" or the "ATM
machine PIN number".

As the most powerful person on the planet once said: "Fool me once,
shame on you, fool me twice ... you can't get fooled again".

You enticed me through the door labelled D-Day but before I walk under
the door labelled ATM I shall be checking for buckets of whitewash
teetering at the top.
