I can be a pretty big tight arse at times. I just don't like wasting money when I don't have to. I could probably list a lot of these but right now I can only come up with the 2 which led to me starting this thread, which are...

- Charging my phone at work so I don't have to use my own electricity.
- Keeping napkins from junk food (fast food) outlets and using them at home.

Seriously, I didn't buy any paper towels for at least a couple of years. That's what I usually use in place of napkins. I finally bought some when I ran out of Subway napkins recently.
