What's smug about it? Do you want to work for $9 an hour? I've actually been there so I'm not sure what you're getting at I don't think you realize how chaotic and hard it is to be a server. Imagine serving a table of 10 and they drop you $20? TRASH.
I've worked as a waiter too in the early 90s when minimum wage was $6.00, but as a restaurant worker I got like $5.00/hr.
Worker as a server is not hard. And I was doing it when I was around 20 at the time. And the tips you get when added to the min wage will blow away any other low end job. All the people working fast food, at the mall, etc.... are getting a flat rate crappy hourly wage. Wait staff get an hourly wage close to it, but tips should literally triple your hourly.
Unless someone works in a crappy restaurant with few customers, anyone working at a normal eatery or even better, a high end place should be getting at least $100 tips per shift. And a shift is never even 8 hrs like most normal jobs. Come in for 6 hrs...... 6 x $5/hr = $30. Plus $100 minimum per shift = $130 for 6 hrs work..... $20/hr.
That table for 10 that gives $20 is an anomoly. How about that easy table for 2 that gives $20? That happens too.
It's not like someone's entire shift is waiting on one table for the entire night. Someone may attend to 50-100 people in a shift, where the tables turnover twice. Even if each person just gave a $1 tip, it still equates to a decent hourly wage when you do the math. It won't make you a millionaire, but it's far better than any standard flat rate low end hourly job.
Another thing too..... it was better back in the day because more people did cash, while now 99% of people do credit/debit, but let's face it. Any cash tip..... nobody is claiming that for income tax. I didn't, and I doubt anyone else I worked with did either. Back then, there was a tip bucket at each station and the servers working each station divvyed it up at the end of their shift. Right into their pocket. Nobody is tracking that for T4 purposes.
Another greedy thing too is that tipping has gone up.... it used to be 10% growing up. Then 15%. Now people seemed pressured to do 20%. At one restaurant (I forget which but it was recent), the credit card gadget had pre-determined tipping %'s. It was 20%, 22% and I think 25 or 27%. Then press F4 to enter your own.
