I once hade to buy a ticket for the "comfort class" section of the train. Comfort class is a lot more expenisve, but all the regular seats were booked, and I had no intent of sitting on the floor. You'd think that pricejump would come with a lot of benefits, but it's really just leather seats, more space for your feet and as much coffee you may want.
While I wasn't overly excited about paying that much for footspace and the smell of leather, I did enjoy the coffee, and apparently I was not the only one. This is where mr. Two cups of coffee comes into the picture. The name explains itself. At first I had thought that he brought a cup for his friend, but it seemed he was travelling alone. Then I thought that he had one cup of tea, just to realize that there were no such thing as free tea in the comfor section (which I think is a bit sad). The man sat there and drank his two cups of coffee.
I was overly fascinated by this, and I never really figured out why he did it. I have this theory that he might have just been lazy and didn't want to go all the way back through the car for a second cup, which I thought was a good idea until I tried doing it myself with little success. The taste of not hvaing to walk was soon erased by the taste of cold coffee.
