We had a great buffet brunch at the Joseph Ambler Inn outside of Philadelphia. It was a little pricey at $35 per person which includes all of what you would expect on an Easter Sunday meal including soft drinks. Our server poured coffee but did not foresee our needs such as giving us clean, new silverware after our dirty dish was taken away. We had to ask for new silverware, soup spoons, cream for our coffee. So, what would you tip? 10% on a $166 bill? What do you consider the norm for buffet tipping?
