Col. Boozy BadgerYou take 10% of the bill amount, because that’s easy, and you double it. Problem solved.
Back when it was 15% is normal, 10% of the bill, half the 10%, then add those numbers together.
You’re welcome, CNN.
Not to say you can’t or shouldn’t tip more than 20%. Just saying the standard customary tip is like 20%, that’s the bare minimum to not be an asshole.
Fade@BoozyBadger Though also I go with "and no less than $2" so that if I go to happy hour with friends on separate checks, and get, like, one beer, I'm not tipping $1 on the check for someone who had to stop by the table multiple times, bring out all the separate checks, etc.

A proper tip is 25% rounded up to the nearest whole dollar. A minimum of five dollars. If the bill is twenty bucks, the tip is five bucks. If the bill is five bucks, the tip is still five bucks. Only having a glass of water? Give your server five bucks. You are taking vauable space and time that could otherwise be spent serving paying customers.
Remember the old saying: if you can't afford to tip there, you can't afford to eat there.
MOVED:They faux'd around & found out!@[email protected] - Goes both ways. I have left a 100% tip on a dinner check for outstanding service - even where there was an 18% customary tip already included. I also write on the check - "Outstanding service provided!"
But I have also actually gotten up and left, with no payment if the server was notedly rude or just completely inattentive. (I do pay the food bill for any food eaten.) But I won't go back to that location again either (not even for takeout), and if needed, will leave a bad rating at review websites to warn others - and for the managers to follow up on, if they read it.
Truffles@BoozyBadger I’m glad you posted this. Not that I’m going to be in the USA anytime soon, but oof, I’m used to 10% meh, 15% ok, 20% good. I didn’t know it had gone up.
Watcher Rat@BoozyBadger once you've worked service, 20% is definitely minimum. Someone could set me on fire at the table and I'd probably still say "I'm sorry, I think I got someone else's ignition."
janusfox@BoozyBadger I've always done 20% and I thought I was going above and beyond. Now I find out I'm just barely not an asshole! Oh no!
I guess we all collectively decided against 15% at some point? Neat.
Kbooki@BoozyBadger ...and then round up is usually how I do.
@kbooki WHO wants to fuck with change anyhow.
That Anonymous CowardWell then you have those lovely older people who don't get that a tip is a majority of the servers pay & more a way for them to flex about not being treated as well as they wanted.
Muzukun@BoozyBadger I typically just double the tax and round up. Granted Cali so higher taxes ^-^;
@Muzukun I include the tax in my 10% calculation.
neclimdul@BoozyBadger admittedly Europe has it right, tipping. But it's also not hard. Also seems like it's printed on 90% of bills anyways

Move the decimal place of the bill to the left one space, add half again as much. (15%) Give twice more the first value (20%) if the service was memorable or much better than average (or give even more).
Ned Weasel@BoozyBadger Or you could just do $1 for every $5 and round up.

@BoozyBadger Out of sheer curiosity, what's your opinion on different amounts for say, curbside pickup or in-store pickup where you aren't necessarily waited on or served?

🐁@BoozyBadger i have funny rules about tipping. With delivery drivers and servers if 10% it's lower than base minimum wage, then I will tip at wage. Even if there was shitty service. After all, maybe they were having a bad day, or the problem was beyond their control.
The end result is that drivers and servers actually look forward to my regular patronage. The Papa Johns's drivers especially let me know this.
