I didn't say ANYTHING about them overcharging me. I said that, if they're getting paid $15/hr to serve food, they're making plenty of money and there's no reason for me to tip them. I don't tip the fast food people that make and bring me my food because they're getting paid to do that.
Now, if they gave EXCEPTIONAL service, I might toss down a few bucks as a personal reward, but for just normal service, sorry....
Tipping 15/20% is done because the workers get paid a minimal hourly wage and then the tip is essentially the payment for their labor services. It's the way the pay structure is set up.
So, since that's the basis for my position, why would this do anything for me at Amazon...unless it raised my prices and I could find the items cheaper elsewhere?
I couldn't care less what companies decide to pay their workers, other than how it affects the prices they charge me. Note that I said "what companies decide to pay". The government making them pay that amount would be a TOTALLY different thing.
