I have always assumed that slow responses in the typical dialogs for failed
password/pin codes were intentional, and were meant as a security measure.
And since I'm not a great typist, I'm afraid I'll someday find that I'm
facing a lockout on some important site...

But £30 to unlock it? Too much.

If I were doing such a task as you chose, I'd probably put on some
Macedonian folk music or some Mozart to ease the pain :-)

Off-topic for a bit...during Desert Storm our unit back in Germany
sent a large container of supplies to us in Saudi Arabia, secured with
a combination lock, but no combo. Calling back to Germany was a dead
end, so I whiled away the hours by trying each 4-digit number in
sequence. IIRC, it opened at 9941. :)

Most sidearms are 9mm Berettas these days. Some special units have .45's
