Hijikata doesn't even hesitate to take it when she offers, although it's fair to say he's indeed quite occupied that he doesn't even really offer a thank you for her efforts. It's only when he finally take a sip of it that he pauses and glances up from his papers over to Chizuru.

"...You didn't have to go through such effort for tea." Because he has always been picky and he's always been able to tell the difference and this is good tea.

He hadn't really thought on the time it took her to bring the tea, but now that he's tasted it, everything seems to have come better together. She shouldn't have felt the need to do it like this... even if he has to admit it's some of the best tea he has had in a very very long time.
