How long does it take for Warsaw CVAC to put stamp to passport if I submit it in person?

I've got the passport request. I need to submit it to CVAC in Warsaw.

How long will it take for CVAC to put visa to the passport if I bring them the passport in person in the morning?

Is there any chance to get the passport back with visa same day in the evening?

Sent it with courier so still don't know the correct answer and don't know whether it's possible to get it during 1 day.
