Actually don't say you are going to "porter plainte" in a café, you will look like a Karen with extra steps
edit : Porter plainte means filling the papers to a Police station to start a judiciary procedure against someone, you'd do that for violence, theft, rape etc...

Yes, exactly what I wrote ;)
Note that this does not simply mean an 'official' complaint, but a formal criminal complaint to police or 'procureur' (district attorney). So if you're unhappy about the service in a Parisian cafe and tell the waiter that you're going to "porter plainte" the reply will probably only be a sneer even more condescending than usual.
