SP, my dear man I do that because I CAN! I have buckets of money that I wipe my can with! Most of the time I light my cigars with 50 dollar bills. I found that a 50 has the right amount of ink that doesn't leave a bitter aftertaste like those 100 dollar bills do. Those cheap 20's taste horrible and it takes about 3 of them to even out the harshness. When you reach a certain stage where money is no object than you too can spread it around.
Gotcha! Just kidding! It's usually done by people with more money than brains! All anyone has to do is look up prices and compare locally(if that's an option!)to see if they're getting a good deal. And then there's those clowns that caught up in the moment like a great white shark on a feeding frenzy. They don't care...they HAVE to have it! Welcome, and don't be a stranger!
