I guess it's my attention to detail (I'm an engineer nerd by trade).
If I really cared, I could buy my gas somewhere else where they don't do this.
To me it's not about the 10 cents (holding the nozzle for a moment will cost me a lot more than this), but more about the principal of it.
I suppose that since no one notices it, nor complains, they can continue to get away with it.
Now back to the original topic!
