It's all about a bit of respect, it's a busy place, instead of pushing the tx button and having a spit, or whining about being cut off etc, just stop have a think that everyone else may not have your experience...
Reminds me of a story doing the rounds a few years back when there was an ATC service at AR.
Grizzled old instructor "tower..XXX fu%king off to the training area for 20 minutes"
Immediate response by well known TWR guy "aircraft saying fu%k on the radio identify yourself........." followed by 10 seconds radio silence then..........
all different responders
"I didn't say fu%k on the radio"
"I didn't say fu%k on the radio either..who said fu%k on the radio"
"me neither I didn't say fu%k on the radio"
and so on and so on...
