Exactly! The price of food continues to go up (seems even more so at Disney), therefor the tip goes up. Like a PP said earlier, 10%, 15% and now 20%. What's next, 50%?!? *buzzer sounds* I don't think so.
As far as tipping goes at a buffet, I have to agree with another PP and say that I start at zero and work my way up from there. I don't tip the bus boy, and I highly doubt anyone else does, why should I shell out money for it just because I'm at Disney? Yeah, yeah I know, they work hard for their money (which is debatable and depends so much on the service expected and received) but so do I, and I just don't hand my money out to anyone for anything.
Sorry, but I really have to lol at this.
So when Disney decides to add a mandatory 18% to our meals, it's all our faults for being more selective about how much and why we tip? If that's the case then I'm guilty, cause I tip based on the service and what I can afford. If that's not enough and Disney demands a certain amount of tip then I'll be eating allot of CS meals and smuggling in PB&J, and believe me, there are many places on the human body you can hide a PB&J.

In all seriousness let's face facts. The economy sucks and most people have less and less disposable income then they did even a year ago. Gas, ultilities and food prices continue to skyrocket, yet our income doesn't adjust to match. So where expected to pay more for all those and then shell out a mandatory 18% gratuity? Sorry, but my income didn't go up 18% and neither will my tip.
Also there are many reasons to not tip or tip very little, and as such it should be completely up to the family getting the service how much the service was worth and what they can afford.
Many families are on a budget and can't afford to tip 20% because someone apparently deemed it "rule of thumb" to do so. Phhfffft! Unless they make it punishable by law and include jail time, I don't think there is any "rule" for tipping. Plus I have two thumbs and sometimes they argue about which rule is right. They've even been known to thumb wrestle over it.
