Before the game, Kilmarnock fans were canvassed for their opinion on McInnes' seemingly imminent move to Hearts.
While they were generally thankful for his efforts, the manner of his exit has prickled plenty.
Should he be in the dugout as he negotiates with another club? There is no right answer, but it is certainly not the best look when his side go on to lose 3-0.
McInnes would not have wanted that, of course. He will be fully committed to Kilmarnock right now if, perhaps, a little distracted.
His players don't have that excuse, and they didn't need one until the last 15 minutes. That was when the energy and legs, having defended with a man disadvantage for 50-odd minutes, started to wane.
In fact, in the first half they were largely the better team and forced Aston Oxborough into a couple of smart saves - mainly from a Danny Armstrong free-kick.
Their ill-discipline haunted them at the start of the season, forcing them to stumble out of the blocks and ultimately cost them a place in the top six. As the season winds to an end, it reared its ugly head again.
Now, attention turns to Rugby Park on Sunday. McInnes against his potential employers, Hearts. An awkward situation indeed.
