I mean we don't want any operations, so we say "we have operations" not "we get operations", is it right?
Thank you so much!

In this particular example it seems it's just a matter of collocation.
Interestingly enough, you use the formula with "have
a something" when the pleasure of the subject and no particular purpose are involved
(that's not the only way you use the structure though) e.g.
1. I had a walk/ stroll/ swim. :tick:
2. I had a walk
to my friend's place. :cross:
-
It might be pleasurable for the subject (you), but it serves a purpose - you want to reach your friend's place, it has a destination point
3. Every weekend we had a walk
around the pond. :tick:
-
You can say 'where' but not for what purpose

P.S. You can find more information on this and similar structures in
The Semantics of Grammar by Anna Wierzbicka. The chapter's titled
Why you can have a drink when you can't *have an eat.
