I find it pretty easy to get out of service because I have a real job and a life.
Every time someone starts to bug me about my lack of service I just state it's so hard trying to do run my business, take care of my home and do everything else on my own that I wish someone could help so I could go. This always does the trick because either the moron I'm talking to doesn't have a clue nor live in reality land and/or preaches love but wouldn't help you if both your arms and legs fell off.
I just turn in a "report" enough to make the big guns stay off my back, and no I've never had a problem of conscience about not going or lying about my "time".
