I never understood the heartburn about a 10% service charge. For that 10%, I am seated at a table instead of searching for one, brought my drink refills, and given real silverware and napkins instead of paper and plastic. Well worth 10% to me to get the same level of service I get at Crystal Palace or any other WDW buffet.
Food can still be taken to go from the Pepper Market (dinner only) to avoid the 10% charge. The tables by the lake are wonderful if the weather is nice. Also, Cafe Rix doesn't charge 10% if all you want is grab n go food.
