Okay, honest question here, but putting on the flame retardant suit . Are the skills necessary to wait tables truly worth much more than minimum wage?
Depends. In a diner or a chain restaurant, probably not, though in a busy place takes a lot more organization and coping skills and the ability to deal with five full tables of people all wanting stuff at once and running food out and etc. than like, working the register in a big box or fast food place. It's also more physically taxing than a lot of min. wage jobs (though certainly not all). However, more comparable, skill wise.
Waiting tables in decent to high end restauarants? Totally different animal, the higher you climb, which is why the waitstaff jobs there are much harder to get and end up paying much more.
In a nice restaurant, a server likely has to know the menu inside and out, and it changes every day, know how the dishes are prepared and what's in them, know the ingredients and what they are (like, you can't just say 'with capers' and not know what they are because someone might ask you what they are), know something about drinks because you have to communicate with the bartender and get drinks from them and communicate with the sommelier. You should know how dishes (and sometimes beverages) go together, etc.
You may well have to be able to memorize orders (lots of places don't allow waitstaff to write orders) which is hard, especially when it's large tops with persnickity people, communicate much more specific requests to the kitchen, deal with the kitchen much more, as they're not just slopping from vats a la Olive Garden, but timing everything specificially and you have to be on point... you have to do more specific side work, know more general stuff - a four-course place setting with a napkin folded into a swan isn't rocket science but it's not a fast food register either, etc.
As someone else noted, the highest-end places have waitstaff who have trained, taken courses in serving, presentation, languages, etc., to better serve and communicate with their customers to provide a whole experience. At that level, it's a career not a job.
I do tip however I only will when the service is good. If a waiter ignores me when I ask for a check or stands around talking with the other waiters and rolls his eyes when I ask for a clean spoon I am not going to tip.
I really don't get the... what seems like searching for any excuse not to tip. The waiter talked to other waiters, no tip. The waiter didn't talk to my kid, no tip... I don't get it; it just seems like... a way to feel powerful over people by taking their salary over such petty little things.
Actual bad service, I'll reduce a tip too; no one is saying otherwise. Talking to other people, not hopping to immediately, not being as engaging as someone would like, that's not bad service, imo.
