My boss is a native Japanese speaker.
In English, when I have a question or an issue to bring up, I can ask "Do you have a minute?" to see if it is an appropriate time to interrupt them. In Japanese, when I tried the literal translation
一分【いっぷん】がありますか？ I was told I sounded like an Instant Ramen commercial.
I've heard another Japanese student use
ちょっといいですか？ but they were also told that's not real Japanese.
I know the word 暇【ひま】but this doesn't seem like an appropriate context to use it, since my boss isn't free, I'm just interrupting him.
How do I politely ask him for his time?
