An aspect of my culture I dissaprove of...

I just don't undestand why chilean people always do their duties the day before and even the minute before.
We always finish our duties in the last minute even if we have time to do it before , I think we (I dont know if this is the right word but...) we "prefer" to do thing in the last minute.
There are some people who have told me that they work better under pressure, so it's sort of a common custome to do things this way.
Unfortunately I'm one of this bunch of people, I'm always doing my stuffs and duties the munite before the dead line. It's just because I'm a little lazy.

Other Thing I relly don't like is when people arrive late to everywhere!
I mean, it's ok when you eventually arrive late somewhere but not always.
I tried to explain the following case to my interviewee:
If you were the boss of your own company, would you like your employees to arrive late and give the files you asked them to give you ,would you like them to give it to you late??
I don't think so.
so..
What do people think about this specific bunch of people?
what woul you do do in the boos situation?
Do you think this costume is ok or is it wrong?
