If its mediocre service, not great service, but not horrible, just OK service then the tip usually falls somewhere between $2-5, again depending on restaurant.

If it was horrible service - for example a rude snotty cocky waitstaff, waiting a long time for service, food comes out cold or it is the wrong order, then I leave a tip of 1 cent. When the service is that bad and the waitstaff just plain has an attitude with me, that 1 penny laying on the table is my 'insult' back to them for such poor service. I've only had to resort this 3 or 4 times so far.
