quickest way to determine a 20% tip is to just double the first two numbers, and put the decimal in teh most logical place

A slick deal was posted for Uno cards at 11:45am. It takes 3 minutes to go frontpage. If each card costs $.02 and there are 100 card, why do I feel like I need to by Uno now?

People who can't figure out how to calculate a 20% tip have needs that are beyond a book to solve...

I'd imagine the book goes a lot further than calculating tips...

off topic but does anyone remove wine bottles/liquor bottles from tip equation and give standard tip on said service? Once heard that expensive bottles should merit the same tip as a cheap bottle given the same service.

A TRUE slickdealer doesn't tip. How else am I supposed to get the meal I ordered? They won't let me back to the kitchen to go get it myself...

The price of the meal should include the cost of getting the meal to my table. Smilie
