Sorry I see It the exact opposite way. Having been a server at a wide range of restaurants, I can tell you that fine dining servers ABSOLUTELY DO work harder on each individual table (and typically provide drastically better service- sure one offs aside, I am speaking broadly) than the server at Texas Roadhouse. They have more complicated procedures in fine dining, a ton more set up pre-shift work, usually more specials to memorize, they are asked to be more attentive to the needs of each guest and in the end are given less tables per night than a server at a fast casual kind of place so that they can provide a higher level of service. So, if I get way fewer tables/people In a shift and folks are employing the flat amount tip practice you described, it would be almost impossible to make a living wage as a fine dining server. Fine dining you might get 4-5 tables in a moderately slow night if you only get sat one full round or one full and a partial section second round.. Most are two tops... So that is $50-60 a night maybe? The same person serving at a “pack em in” food trough kind of place like Texas Road House is probably giving AWFUL service by comparison and is making 3-4 times as much. Not very fair at all TBH.
As to whether they “should” pay servers more and rely on tips less? Yeah they probably should, but the fact is they do NOT in America, we all know it, we all know we SHOULD tip if we are going out and I hope my illustration above shows why the percentage method is much more fair. Doesn’t mean you cannot tip more or less based off situation.
Which leads me to my biggest point: I have not been service industry for a long time now but I beg all of you- if you are too cheap to tip, STAY TF HOME. Especially now. They are literally putting their lives on the line to serve you, Fighting restrictions that prohibit the restaurants from even getting busy enough to make money and it is way more frustrating for them than it is for you. Worst case, if you go out and can’t get sat quickly or have some other minor inconvenience due to safety measures... You should EXPECT THAT, and be ready to deal with it... So, Please- be nice, be patient, and Tip WELL Or- again- stay HOME.
