When I was younger, we spoke about someone's mother, not someone's mom. "Mom" was what you called your own mother. Now, "mom" is all you hear. Is it an attempt to become more familiar with people? Sound more folksy? I don't like it, and I'm starting a campaign to get "Mother" back into our lives. I'm starting a GoFundMe page, and I'll post the link later. Thanks for your support. (Yes, I am kidding about the GoFundMe page. Unfortunately, I had to actually say that I was kidding.)

The same applies to "dad," of course, but people tend to ignore fathers. They're either at work or fishing/golfing/gambling/drinking.

I agree with you 100%. Here in Ontario, we pay 13% harminized sales tax. Federal GST + Provincial sales Tax. It is not the extra cost but the principle of paying a tip based on taxes not on goods and services. I just calculate the tip manually based on the sub total 15% is easy, 0.1× the subtotal + half that again. 20% of even easier: 0.1×subtotal×2.
To be honest, I would rather the waiter was paid a decent wage and the cost added as a fixed charge to the cost of the meal. The tip is more like a bribe to get decent service. I have heard the origin of TIP was To Insure Prompt service.
However that does not seem to be the way our culture works so I guess we have to live bribing people to get what every customer should expect as their right, good service. I'm no faulting the wait staff. They work very hard. I blame the restaurants for not paying adequate wages and expecting the customer to make up the difference.
McDonalds and Harvey's for me!
