I'm one who believes that tipping should be based on the service not the amount of money you spent on your food.
My standard is $5 PP and more if the service was above and beyond which generally even at WDW its not.
Only time I tip more than that is when I have 6 or more and the gratuity is automatic.
I realize that not all cultures tip and I assume that is the case for the OP.
I would recommend dropping some TS meals in order to reduce the amount you are tipping.
I mean 14 meals is entirely too many TS meals in my opinion anyways.
QS meals at WDW are often times close to the same quality that I get at a local diner or even chain in which I do leave a tip but the nice thing is no tip needed.
