In the good old days, in the British merchantman service, it was customary to sign on crews under two separate sets of articles; one set at a certain rate of pay with the privilege of “growling,” and the other set with an extra pound a month but “no growls.”
You need not ask a sailorman which set of articles was the more popular. The right to kick goes with the freedom of the seas. The American merchant service, always notoriously hard, didn’t even offer the “no-growl” articles!
Sometimes growling is permissible, and one of these times is when you feel that your voltmeters and ammeters are not telling you the truth.
