On ne parle pas affaires au Continental

Missing, extremely new, or very obvious to obtain.

A reference to the John Wick film series. The Continental is an international chain of luxury hotels that function as neutral territories for members of the criminal underworld. The hotels have strict rules, and the most unyielding rule is that no business can be conducted on Continental grounds. The hotel is a sanctuary for assassins and mercenaries, meaning no fighting, killing or carrying out contracts is permitted in these hotels.
