Work time was work time, most always. There were few exceptions, and those times, well, Barty had gotten himself out of work. He hadn't claimed to be working. The MLE was one of the more sexless jobs, when it came to paid time. And as per private life, well, Barty was fine using as much of it as he needed for any given case, but he didn't overwork them without reason. They had a purpose, for him, and that's what any interacting was about, in the end.
"They get their time off," Barty nodded, "I don't tend to call them in for something unless I really can't handle it on my own." And that rarely happened. Besides, he trusted other people more for that, like Evan.
"Not that kind of drug," Barty chuckled, "You'll be using a cane before I ever need to use those. Daily exercise." He grinned, eyes sparkling. The idea of Rab needing a cane made Barty laugh but so too did the idea of him needing help in the bedroom.
