I either pay or drive around for another two minutes, which, in an urban area, probably equates to about half a mile extra driving. In the grand scheme of the typical Western lifestyle the extra fuel used and carbon footprint of this is negligable, and is certainly not sufficient to justify a something-for-nothing entitlement attitude. Or to put it another way, if you do decide to chance it, then accept there is a risk you will get caught, and if you do get caught, take responsibility for the consequences of your decision, and learn from it, instead of pouring out a load of pathetic weak excuses as to why the rules shouldn't apply to you.
More likely, if it is a local journey, I would leave my car at home and use my bicycle, then the parking is free, and the carbon footprint and fuel used is minimised.
