When I flip a coin, I reach up and catch it in mid air, then slam it on to the back of my other hand. I feel fairly certain that those two actions would negate any bias discussed in this article, and quite possibly introduce their own. If you know enough about a particular way of flipping a coin, you could know whether the chances are off from 50/50, but if you know that much, you could either devise a way for the result to be in your favor most of the time or you could ask for the method to be changed to make sure the other person isn't cheating. In either case, coin tosses are often done in casual circumstances where close enough is good enough.

In a day you can learn to get about a 70%+ swing in your favor by timing the throw and catch, and if they call it in the air, you can either flip it twice or just once when you slam on your hand. All fair coin tosses should land on a flat surface. Felt or carpet is better than tile because it reduces the odds of the coin spinning when it lands, which is weight-biased.
