I understand that けれども/けれど/けど means "although, however, but", but I'm looking for the daily usage of it.

It looks like that native Japanese use this particle not only when they are trying to contradict two things. Would any native level Japanese speaker show some example of けれども/けれど/けど that will make me sound more Japanese please?

An example would be (I heard this when I was buying a train ticket, someone said to the train station staff):

> 
> ◯◯に行きたいんですけど…
> 
> 
> 

Doesn't make sense to me. I suspect this is due to Japanese culture.
