Mandatory Tip?

I was listening to the radio the other day and the talk show host came on the radio saying that some restaurants are taking about starting a mandatory 25% tip. I almost laughed when I heard this. I just ate some food at a Denny's and I was so dissatisfied with the service that I didn't leave a tip and I even considered leaving without paying. Of course, I had to do the right thing and pay for the food I ate, but there was no way I was leaving a tip. I like Denny's... normally... but this particular visit I paid twenty dollars for my waitress to bring me a coffee, water, and a little food. She never offered me a refill on my water or even brought me a check. I had to go to the register to get my check and pay. I'm a pretty nice guy and usually leave a tip if the waiter/waitress does a mediocre job and I try to leave a generous tip if they make me laugh or even just keep my water filled. Needless to say, for me, the tip is a sort of grading scale. The standard 15-20% tip is a good rating, while anything more than 20% is a great rating. If you don't get a tip, quite honestly, your service was bad and needs TONS of improvement... or I'm broke... either way, make me laugh a little next time. If these restaurants start charging a mandatory tip, I will have to stop eating out. It already costs around $10 for one person to eat out somewhere decent, with a 25% tip, that's $12.50 plus tax. Now, for those of us who aren't single, that's a minimum of $25 every time you want to go somewhere even mediocre. That's going to cut my eating out down a lot. I don't think this mandatory tip is a very good idea. If there are other people out there like me who realize how much of a difference $5 can make, then those people are likely going to quite eating out also. Translation: less people eating out = less tips for waiters/waitresses = less money for waiters/waitresses to spend = larger demand for better jobs = higher unemployment = less money = even HIGHER demand for better jobs... it's a vicious cycle and I AM taking things a bit extreme, but let's face it, I'm right. So, waiters and waitresses earn that tip! Everyone else, if they earn the tip, give it to them! generosity is helpful!
