Yes looking at the superficial literal reading it appears as above however a more in depth view of the whole episode plus future blessing from Yitzchak give a different story.

The written Torah was given long after above events and considering the oral Torah was given at the same time (again according to the traditional Jewish view) – I do not see how you can interpret the stories of our forefathers without the Oral Torah considering it is not a primary source from that time anyway.

A simple short alternate view is given here

It’s one thing to live by a code “I will not queue jump” – this purely requires self-discipline.

For some of us, it’s a more difficult dilemma when we are in the queue, only to have someone we know in a social or professional capacity approach us and ask if we can let them in.

If you let them in, well then you’re opening yourself up to all that is wrong with queue jumping, as you have succinctly outlined.

But if you do not let them in, then offence will surely be taken, and unhappy consequences will likely arise.
