Exceptions are a fact of life. If you are unknown, then you get on
the back of line like everyone else. But if you are known ("on the
special party list"), you get special treatment and can avoid standing
on a line. Its always possible to learn that you are not a
troublesome, a regular party dude to get a pass, but its all still
about be recognized.
After 25+ years, the uncertainly principle for relaxation protocols
should no longer be a quick out. There is simply no excuse today to
continue tolerating violations of protocols or relaxing it for all.
Exceptions to the rule of thumb has to be about trusted exceptions -
not risky exceptions.
