Jury duty excusal on placement

Just had jury summons and will be on an internship placement at the time of the trial. A mate recently got excused because his summons were during uni exams so I think qualified under "abnormal inconveniece" but this was with a special letter from the university. Should I even bother trying to get excused? How likely is it that it’ll get accepted. I am a student with no dependents, and this is in Scotland.

You could ask but why is the Internship such a barrier - is it a very short placement?
Some employers encourage their staff to do their duties as a citizen and won't write excusal letters.

Sadly, some will also end your contract if you aren't available.

Oh, that's harsh and selfish of them.
Jury Service should be seen as a standard and typical responsibility. It's a shame they put their needs above public duty.
One of my past employers was very supportive and would not write excusal letters as it expected staff to do their jury service. Then again, it was in the public sector which has an emphasise on public service.
Im still trying to get my head around an organisation arguing that their low or no paid intern, the most junior member of staff, is so operationally important, that their absence would inconvenience them.
I've been excused Jury Service in Scotland 3 times due to it clashing with pre booked holidays and the courts tend to come back quickly with new dates.
