This was Riverrun guildmaster, seems like he had no quests. But at the end, he sounds like I declined a job.
- Do you happen to have a job for me?
- Sorry, but you should be back another day.
- OK, farewell.
- Well, the job will be available for few more days I guess. Tell me if you decide to take it.
Screens were taken after asking again, but aside from first line, dialogue is identical.

Sounds like a dialogue between two spies undercover, if you ask me.
