Want to talk about cheap people? In California, they have these guys, like the Road Rangers around here, that will help people on the interstate system to keep traffic flowing. Stuff like change a flat, give you a jump if you're stalled on the side of the road, even supply a gallon of gas for you to make it to the next exit. Well, when gas starts to edge up (like it has again recently) people will drive until they run out of gas, get a free gallon, drive until they run out of gas, get another free gallon, etc. There are some really, really cheap bastards out there who will take advantage of every chance they can get to not pay for things.
P.S. - 100 octane at my usual station went up $1/gal over the past month, and that stuff rarely fluctuates. FTL.
