To get a table

To get a table
 

I’m not entirely convinced by my use of ‘coger’ below. Is there a better option?

You can never get a table in the library on Fridays.
Nunca se puede coger una mesa en la biblioteca los sábados.

Many thanks in advance.

It's correct, although maybe the preferred expression will change from region to region; in some countries this would never be said.

"Alcanzar" would have been my first choice. Not like all tables are running away from you, here it means everyone took a table before you could find an empty one. :)
