Yes, you are paying for a more expensive, better quality food at a "nice" restaurant (in theory). You are also paying for better, more knowledgeable service. I know I do more than servers at places like, let's just say Bob Evans (not that there is anything wrong with it- just an example here- the servers there work hard, too). For example, they are not running alcohol and multiple courses. Also, as I said earlier, the restaurant I work at is very strict with their steps of service. What a guest might think is a "nice touch" is actually a planned step of service. For instance, when we clear the table, it must be all done at once, so you have to gather enough servers to "swoop in" and get it all. We then "crumb" the table, making a pass over the table to remove all of the crumbs (so you can put your arms on there without getting crumbs stuck to them). We then box your leftovers and return them to you. Not that this saves anyone's life or is the entireity of my job, mind you. They are just a few examples of some of the things we do that set up apart and warrant 20% when executed properly. I am really not complaining, at least about the guests where I work. Everyone maintains a 18.5% average or higher on a regular basis, so we must be doing something right!
