People aren't happy with this tipping hack from CNBC

So, what was their genius hack that would make going out for meals so much cheaper? Well, rather than tipping 20%, CNBC suggested that you simply double the tax total that’s added onto your receipt. The amount that your meal gets taxed is itself a percentage of your meal cost, and it’s usually not a significant figure. Therefore, paying two times this total still works out to be cheaper than handing over a fifth of your overall price.

For diners, this allows them to walk away with a few extra dollars than they would have done otherwise. That might not seem like much, but it racks up over the course of a year. The more you dine out, the more money you save by following this tip. In a matter of months, you’ll have saved several hundred dollars without even realizing it. Unfortunately, not everyone benefits from this hack.
