That's what I meant, you can tell I don't use them in the city after midnight (because there is only one train home after that, and the people on it are way too drunk for me to want to take it)

It's a shame that in London you can get an Oyster card, and not have to worry about any of this, it calculates the best rate for you based on your usage over a day or whatever.

In New York, not only do you have to deal with those stupid machines that give you dollar coins, but won't accept them all back, but you need to figure out what you need, because they can't do it for you.
