Yup - dinner with my wife and kids - I'd better be in & out within an hour or so. Granted, I will choose the restaurant with the expectation that they can meet that objective. Obviously we only going to target family-friendly establishments for those meals. If it's just me and my wife, then I'll take a little more laid back approach. As long as I'm seated, drink orders are taken and menus are in our hands within the first few minutes, I'm usually happy. Sometimes I get a "gut feeling" that things are "off" and we'll politely excuse ourselves. Usually that feeling comes when seating, drink orders, appetizer orders, etc. aren't taken in a "reasonable" amount of time, or if I look around the restaurant and a lot of folks don't have any food in front of them and seem to be looking for the waitstaff.
