It sounds like a different situation. I don't think Amazon drivers qualify as "tipped" employees per the IRS definition. Tipped employees are those who regularly receive a substantial portion of their income in the form of tips, like restaurant servers. But, as a general rule, when a customer gives a tip to an employee, the tip is the property of the employee, not the employer.

When you go to Katie Belle's and order a Diet Coke, you should leave a 100% tip.

Tipping
 

The best way to tip is to give cash as this way it goes directly to the server without taxation. They put the cash into a pool or in their pocket without the IRS sticking their hand in the workers pocket every minute.

I don't support assisting people to cheat on their taxes. Tipped employees already get a favorable tax treatment by paying income tax on only 8 percent of the restaurant gross sales, even though they usually receive more than that in tips.

Why would you encourage people to cheat on their taxes? Or is that ok in your book?

Court Ruling, How About Customer Ruling?
 

Another poster wrote she asked the servers wages and was told the server was paid $6.85 per hour. Consider below:
Did you ask her the value of her tips are for a complete schedule of work, whether 6,5,4 or 3 days per week? If she has good repeat customers she can easily double that figure. If she provides courteous, prompt service [allowing for the kitchen being inundated with orders at the same time] servers can make double or triple the "actual wages" they receive from their employer. If the employer allows them to keep all their own tips [not pooling them with all the other servers and divided up at the end of their shift or day] then it is possible to make a reasonable wage [I didn’t say livable wage depending on housing expenses where they live] as a server.
In my life experience I have had personal friends go to college and while in school, work as a bartender or meal server. When they graduated college some of them stayed in their college job because the entry level wage for their college education was well below what they were earning in their college job.
Please consider the mandatory [after 5 years of annual implementation] of the $15 minimum wage law going into effect in Florida and other states. The industry in general have already figured out a work around for this. They will only hire part time workers whom the law will exempt under its statute. The fast food industry has been experimenting with automated robotic food preparation systems which will augment their part time workforce. Overall everything seeks its own level and this situation will do the same.
Good servers deserve good tips for their efforts. I reward based on personality [friendly, courteous] quality of service [attentive, responsive to requests]. 10% poor, 15% quality, 20% outstanding. Personally tipping in the US has gotten completely out of hand. When I worked in a trade, we received no tips. Now these so-called experts are telling us we need to tip for things like having furniture delivered, dry cleaning service, self-service counter help, mail delivery, etcetera. Sorry folks, if you want a better wage get training in a better paying field, learn an in demand skill, go back to school part time or enroll in a training program. Low wage jobs were never intended to be a career, much less a “living wage” position.

So on a $50 dollar bill tax $3.50 you saved $0.70? Bless your heart.

Says who? Where is this written?

Very well said

Darrells' Diner charges a .50 service charge.

It used to not be....but now I'm not so sure.

Finding it easier to use Doordash. Often less expensive with all the promotions. Same food, less hassle

50 cents? What is the point of that?

Doesn’t work that way. Read the IRS guidance

The most I've paid for a service fee for using a credit card at any of the restaurants around here was 37 cents regardless of the amount of the bill. To my understanding restaurants used to absorb that as a cost of doing business but during and after covid and the present economic situation, they no longer can.
