This is especially important if you plan to tip a low amount. Regardless of your personal politics toward tipping, if you tell someone in advance that they won't be getting much in return for their service then they are less likely to give you good service. Even if you plan to tip well, disclosing the amount in advance can have the same effect of diminished service quality. This applies to tipping in general, actually.
A tingly hand or arm is often the result of compression in the bundle of nerves in your neck; loosening your neck muscles releases the pressure.

Before i started doing this, a bartender at my favorite bar straight up padded his addiction wallet by writing in a fatter tip. I probably lost about 300 bucks i didn't spend before i caught on. Once i started putting $ in front of my dollar amount, it stopped.

Rotate the map. Or if you're like me, in Google Earth rotate the globe so that north is longer pointing up. (On a flat map, this would be like rotating the piece of paper so that South America is on the left and North America is on the right.)I find that this makes familiar shapes just different enough so that I start to really look closer at the distinguishing features. I find that I also appreciate the relative positions of things a lot more once I've looked at the globe at different rotations (and with the "camera" in many different positions).And, like in any healthy relationship, change it up from time to time and try different rotations and positions.
I made a tip jar for myself. I currently use a credit card holder and change is always loose in my pockets. So if I have any change when I get home I just put it in the tip jar. This way I am able to save up a couple of hundred bucks a year.
