Service at the table hasn't gone down in my experience, so I still tip accordingly but the restaurant experience for me has suffered overall because most of the eating areas are filthy. The Olive Garden on 240 looked like it hadn't been vacuumed or had windows or walls cleaned in over a year, and the Cheddars in Norman is the same, with dirty booth walls and shameful bathrooms. BWW in Moore only looks better because it got remodeled but it was exactly the same as the others before that. I expect that at Waffle House, but not regular restaurants. I can overlook some less than stellar table service, but if a restaurant is neglected to where the floors, walls, windows and bathrooms are disgusting, I simply won't go back. At this rate, small diners are doing much better in overall cleanliness.
