The risk is not only slowness but stacked vulnerability
A construction release section does not hurt the day simply because it is slower.
It becomes expensive when waiting time, toilet need and hunger all become uncertain at the same time.
Handling the basics before release usually buys certainty
A toilet stop, water and some food before the queue are valuable because they reduce the pressure of the unknown segment.
For seniors and children, that certainty is often worth more than hoping for a nicer meal later.
Eating after release works only when the next node is truly reliable
If you know that a proper town or service point sits just beyond the release section and the wait is genuinely short, a delayed full meal can make sense.
The key is actual route knowledge, not optimistic map reading.
The mature pattern is to split the problem into before and after
The best answer is often not solving everything on one side of the release point.
It is lowering the risk before the wait, then doing the fuller meal or deeper stop after the uncertainty has passed.
