As a very frequent visitor to the USA I wanted to add a little to this thread, about tipping generally in the US.
Recently I’ve noticed more and more (mainly restaurant & bars) making ‘tip suggestions’ at the bottom of the bill “to save you having to work it out” – these so called ‘suggestions’ begin at 18% & also suggest 22% & 25% & show you how much you should add to the bill. For example, 18% of the total bill.
The issue here is that tips should always be based on the UNTAXED portion of the bill and not the total bill – many outsiders are not aware of this & they leave 15-20% of the bill total.
For future reference, only leave a percentage of the untaxed portion of the bill. If your bill is $100 & $20 of that is tax then, the tip is paid on $80. Over a year, this can add up to a significant amount.
My company now has a policy of maximum 15% tip at restaurants/bars(or it’s from your own pocket).
No tips to cab drivers & to always use Uber if possible as tips are not required.
