e. I don't think what is considered proper is a personal opinion. It is based on manners and generally accepted rules.
Might I respectfully suggest a course or reading a book in Sociology?
There you will learn that while "norms" are based on what is general to ones culture, no one's "norms" are any more right than the other.
As I stated in a post a a while back in a separate thread:
Its normal to eat a cat in some countries. It is not acceptable in the US (which is where I live). However, if I wanted to eat a cat (and I don't) I wouldn't let what society dictates tell me if I should or not. With respect to the law, if I want to do something that is considered "abnormal, unusual, or not with the masses" I will. It doesn't make me or anyone else a bad person, a prude, a grinch, or a flake if I decide to tip a different amount than they do.
For those telling me I should eat elsewhere, I have already stated that I avoid restaurants with a mandatory gratuity. I am not guaranteed good service so I will not guarantee a tip of any percentage.
If you really want to harp on someone, complain to the restaurants who don't pay wait staff even minimum wage. I always leave some kind of a tip, however, I will never under any circumstances leave a tip that comes up to 20% of the cost of my meal at Disney. I have spent $40 and left an $8 tip before at a local place. Disney's prices are more than the average restaurant which makes the tipping get out of control when you figure it at the %20 amount.
If a person is waiting on 10 tables at once and the average bill of those tables is $200 thats a total of $2000 for one round of tables. The wait staff would get $400 for those 10 tables. Even if every person sat for 2 hours thats still $200 an hour for being a waiter/waitress. Nurses and some Doctors who have college degrees don't make that. We all know that Disney's tables generally stay booked so its not like he or she will have a "down" night. I will not tip someone on an entry level job to the point that I am contributing to them making more than someone who has vested money into a college degree and in the cases of mandatory tipping, this is what is taking place.
Im not saying what I do is right. Im not saying what you do is right. Im just saying that I won't cave to society when it comes to tipping. I will tip what I think is fair for the meal and service I have gotten and under no circumstances at a restaurant priced as those are in Disney will it be 20%.
Just because a meal costs more doesn't mean the wait staff is doing any more work then they would at the same kind of restaurant who has lower menu prices, which would result in a lower tip if based off total price.
