Look, either it is easier or isn't. If it is easier then there is your reason. If that reason isn't good enough for you then tough, because you don't know what it is like to be them. You don't know what else they do that is maybe harder than what you do that justifies to them taking this easy option.That was in response to your comment, since clearly EVERY person who goes one stop has a really good reeson.
But the fact still stands that I see LOADS of people go one stop. I have people at work who freely admit it aswell, eventhough it actaully is more hassle. I am not making this stuff up, sure there are some genuinely good reasons, but on the whole plenty of pople are just clogging the system up unnecessariliy.
If it isn't easier then you really need something other than "they are lazy" as your reason.
