Alternative for "ageru"?
This is bugging me for awhile, I know that when we want to say we do someone a favor or we give someone something, we use "ageru". However, when we talk to a stranger or someone with higher status, we shouldn't use it or we would sound rude. So,...which verb should I use here, in those situations? For example, "I'll do it right away for you, sir" ("it" here can be anything, probably just a task that the boss wants the speaker to do). How do you say that in Japanese?
Thank you in advance.
