Oddly enough I was thinking of the times I have to buy a paper and came up with very few instances. All involve not having a free wireless connection available, which is increasingly rare. Here is my list of times I would have to buy a paper.
1. Stuck in an airport.
2. Stuck at a train station
3. Stuck in an extremely boring ballet/opera/musical(are there any other kind?).....
4. Having trouble thinking of another.
5. Stuck in a public restroom....
