Only tip your server at restaurants and food delivery people, anywhere else is a scam. Servers and delivery people can be legally paid way less because they're expected to live on tips, its shit but its how it works. If you don't tip them they could have basically worked for you for as little as 4$ an hour. If you're worried about amounts, just go for 15%, its the expected amount. Skip if they suck at their job though.

To sum up, if you work in a business that relies on tips, you will defend the crap out of tipping and will be biased towards tipping uncontrollably.

If you are a business that wants to squeeze every penny, you will encourage and propaganda tipping as much as you can.

If you are anyone else you will wish for something different.

I recommend that you tip when the app says to tip, just simplify your life and if a screen says add a tip choose the minimum for now and don't worry about it yet.

Definitely tip. If you think the whole system sucks that's fine, but don't take out that frustration on the likely vastly underpaid employees

You need to tip places where you sit down to eat with waiters, yes. ~20% of the subtotal before tax. Don't be intimidated by those little tablets asking for a tip for places where there is no table service, there is usually a no tip button. Just relax and don't hit a button right away. They make it a little smaller.

When in Rome…

IMO you can opt out of the "tip at register" sort of stuff if you want. But if a waiter is coming to your table to take your order, bring your food, refill your drinks, etc. Then you really should tip 15%. Waitstaff generally are paid less than minimum wage and it's because of tipping culture.

Here is a source on what they are paid by state. The 2.13/hr states are the ones you really should tip.

You should take a look at https://en.m.wikipedia.org/wiki/List_of_US_states_by_minimum_wage and see what the minimum wage is in the state you are visiting. The minimum wage where I am is one of the highest in the nation so I don’t tip anymore.

Edit: I am aware many states have below federal minimum for tipped employees. My point was if they’re visiting one of the states with a high minimum wage, they should forgo tipping. Nobody below bothered to link it, but here's the minimum wage page for tipped employees: https://www.dol.gov/agencies/whd/state/minimum-wage/tipped. It's worth noting that even in the states that can pay tipped employee as little as $2.13/hr, the employees never actually make less than the federal minimum of $7.25/hr because the employer has to make up the difference if the employee doesn't make enough in tips, not that $7.25/hr is even remotely a livable wage in 2023...

Regardless, tipping is an inherently flawed system, and it's not the responsibility of the consumer to pay specifically the server a living wage while everyone in the kitchen suffers (I would know, I've been there). If you're not happy with the wage laws in your state, get involved in politics and exercise your right to vote to do something about it.

Tipping culture used to be a courtesy, but now it’s been classified as part of salary so restaurants don’t have to pay minimum wage to their waitstaff. You’re not required by law to tip, but depending on the place, waitstaff will remember if you tip or not and how much.

Tipping has not gone away except in some places where they explicitly say it’s not necessary.

Typically I double the tax amount and leave that as the tip. I will also round up from there if it’s an uneven amount to reduce change. Finally, I’ll pay more if service is exceptional or I’m being served by someone I know personally or if they’re doing me a favor.

Some places include tips in the bill, so be careful. I also usually don’t tip if picking up food because there is usually no guarantee that my tip would actually go to the people who actually prepared my order.

I also tip other service jobs (Barbers, mechanics, plumbers, etc..)
