Okay, I'm throwing the Penalty Flag at Sauer Grapes for Unsportsmanlike Conduct!!!
#1 - WHATEVER you tip the waiter/waitress is split between the Host (the jacka$$ that asks "how many in your party") and the Bartender - no MATTER if you had drinks or not. The Chef/Cook doesn't get sh*t. Anyone who has ever waited tables knows this.
#2 - You use a cabbie/hack to get you from Point A to Point B as fast as you can, right?? You're not paying for the scenic route, right?? So, in effect, you are actually relying upon his/her knowledge to get to/through and in/around any traffic/congestion as fast as they can, right?? and THAT DOESN'T DESERVE A TIP??
Okay, rant mode off.
As for Kane, who is even remotely surprised that yet ANOTHER "professional" athlete did something stupid?? Million Dollar contracts and dumber than &^%$ when it comes to common sense.
