If something is unacceptable to us (like, for example, never sticking to plans, acting surprised at being cut off) that is because we believe it breaks the rules of the game. But that assumes two people are playing the same game. Now, if two people are playing two different games (and that is clearly the case if one has a goal and the other does not), then there are no rules. Anything goes.
(Separately, I think one of the reasons people don't stick to plans anymore--anywhere, not just Argentina--is because of the advent of instant communication via cell phones. Once upon a time, people had to stick to agreements, because there was no way to get in touch with the other person to change them. Since smart phones came in, it is much easier to agree to plan that we aren't really that keen on or committed to, or leave a plan a bit vague, because it can be instantly renegotiated with the other party right up to the originally appointed hour.)
