Alexius collects his task and looks around for Huang or anyone else collecting eight people's worth of work. There they are, conveniently clustered. "Hello Huang. I've got a freshman bathroom cleaning, that for cafeteria is fine with me." 

"Oh, good," she says, "which one -" She offers her cafeteria cleaning slip.

He shows his. It's in the rough vicinity of the 200s. 

"Oh good, I have the one across the hall already, I can do them at the same time." One by hand to recover the mana spent on doing the other by animate mop. Swap!

"Thank you!" Alexius could maybe animate a mop if his life depended on it but his cleaning is going to be done the old-fashioned and mana-productive way. He sets about introducing himself to the maintenance track kids, mentioning his plans to offer lookout/bodyguarding services for larger groups later in the year and to offer the doing of homework assignments, even for classes he's not in.
