At a Japanese wedding reception, one of the speeches is given by the shuhin, the guest of honor. The wedding magazine Zexy advises couples to give this speech to jibuntachi yori meue no hito, a person above them in standing, with whom they hope to keep a relationship.
If the guest of honor is the boss at work, Zexy suggests asking in person and in private: Puraibēto de onegai shitai koto ga arimasu. Ojikan itadakenai deshō ka. There is something private I would like to ask. Could you spare me some time?
