Izroth, "I will admit, it is unlike a mercenary group to turn away gold coins."
Haishe, "Would you have been willing to speak with me directly otherwise?"
Haishe was correct. After their last encounter, Izroth had no reason nor obligation to hear him out beyond fulfilling his end of the agreement.
Since that was the case, it was clear that Haishe had more than one purpose in contacting Izroth.
Izroth, "No, I suppose not. Then, what is it you wanted to discuss?"
Haishe, "Before that, I'd like to extend my thanks to you."
Izroth, "Oh? I don't recall doing anything that warrants your thanks."
