You assume that the student had the experience to judge that it was a tight spot. I don't think that's a fair assumption.
I don't know the specifics of this particular case, but I can imagine a scenario where a student based somewhere where there's plenty of taxiing space has little experience at all taxiing in tight spaces, and so is not able to recognise the situation when it's appropriate to shut down. Especially if at a foreign aerodrome, if the situation seems to be "the norm", everyone else seems to be managing just fine, you're holding up a bunch of people behind you, you're not even sure how to explain what you need because the R/T for that is something that you haven't practiced, and this situation didn't arise when you practiced with your instructor the first time round.
It is very easy for an experienced pilot to say what one should do because you're using your experience to recognise is appropriate and
you know that others are likely to agree that your chosen course of action is a reasonable one. It really difficult
when you're new to something to stick your neck out that, for fear that the option that you're considering won't
be considered reasonable afterwards.
I don't know if any of my speculation above applied in this case. But neither do you. Unless you know otherwise, I don't think it's appropriate to be berating people. The important thing is that people take responsibility for their mistakes. Berating them for making mistakes in the first place serves no useful purpose.
