I have yet to encounter an automatic tip calculation that doesn't base the tip on the total bill including taxes. It’s a pretty infuriating cash grab. Not only am I directly having to pay an employee’s wages so the restaurant doesn’t have to, I’m having to tip the government, too? (Yeah, I know the government doesn’t get the tip)

Tipping by percentage never made much sense to me. I order a coffee at a diner, the waitress only gets a 42 cent tip? She should get more if she has to carry a plate of food? She checks on me the same amount. That's a five dollar tip at least.

whenever I see a "suggested tip for your inconvenience" I feel the urge to research (aka google) their reported earnings for the last economical year, calculate their profit margin and write that in the tip line and to pay their employees better instead of trying to shift the costs onto the customers with scammy guilty conscience. Fuck establishments like that, especially those who are then trying to conceive you ONTOP of the already bs tips

And they still tipped?

My tip would have been 0 right there and would have included a complaint with police

The whole tip thing is a scam to begin with.

Also, you're supposed to tip on the subtotal.

When I see they have made a "mistake" like this. I don't correct it.... I make my own mistake and give a smaller tip than i would have

Tipping, specifically in the original context of restaurants, I will still do, simply because the government needs to change the minimum wage so that servers are included. They're currently a protected group that is allowed to be paid far less than minimum wage, and they are supposed to make up the difference in tips.

In every other context, wow me and I'll tip you, otherwise, don't expect shit.

If you did your job as you are expected to do, then I don't see why I need to tip.
