Most of us don't live buildings with a doorman so we can skip that, but we should be tipping landlords, delivery drivers, and handymen this holiday season. How much? And how do we get the tip into the hands of the trash collector?
I took my daughters to a fast-casual food court the other day and each restaurant had an iPad cash register, which meant that I spent 12 to 20 percent more than I would have with other payment terminals. It's too hard to say no to the tip!
