Being cheap ?
Dude, I drive a Volvo !
While I don't mind paying for quality, I detest paying for rubbish !
I've only recently gone cheap on maintaining Hägar because the expensive maintenance wasn't paying off, so I feel it's no longer worthwhile.
I use 1 paper towel instead of 2 at work, as 1 will do the job (though barely).
A good, well filled dishwasher uses less water than doing the dishes manually.
Working at a chemical plant, I try to run the place more energy-efficient, as it's a very power hungry beast .
We go through more gas in a few hours than most households use in a year.
That's the place to make a marked difference, energy wise.
