Q: Since this is a meal with unlimited refills. And it is also cheaply priced. How does it affect tips and time and effort

A: I bet the servers at Olive Garden hate it when their table orders all you can eat soup and salad. It is a cheap/low ticket and the people probably sit there forever.Plus most people that sit forever at a table don't consider leaving an extra tip, which they should because they kept that table from being reseated. I don't think the endless Pasta dishes would be to bad, because not to many people can keep eating full entree's of pasta.
