sorry for my tone in my post,
i didn't mean to suggest that what you were doing
wasn't important, or that her work was more important than yours
or that she was acting professionally ...
but in the end, it was only a few minutes that you lost.
i hope you were able to finish what you were writing after
you were allowed to sit down again. sometimes a short break
gives the distance needed to find the right words &c
back in the days i was writing long dense papers, i didn't have a laptop
but papers, books xeroxes notes and junk spread out where i was camped out.
i was asked to move once in a while, l left a notebook out and as i was packing up all my junk
and moved to another place my mind was still digesting the stuff i was reading & thinking about
so when i finally sat down and sprawled again, i had more notes to write &c.
not quite the same thing, i was a guest in another university's library borrowing space, not in a public space ...
and it was a drag to collect my stuff and lug it somewhere else, but in the end it didn't really matter ...
i liked to study/write where i was, and i knew that id be asked to move from time to time ...
(and if i didn't comply i probably would have been asked to leave, and not return )
