@aberrant68 The most polite way to get the message across you're trying to pass to them, IMHO, is that if they don't care about gracious professionalism, this isn't the program for them. There are other programs, but what this one seeks to do is not tied to the machines generated alone.
(... categorically true. I can tell you how many of these machines become coat racks or spare parts in five years. It's a program for building students, not robots. ;) ).
I wish you best of luck; it's never an easy conversation to have.
@mtomczak Thank you. I just talked with them a bit more, and uh, I underestimated how far they would go. I'll just have to deal with comments about how I think they're so awful for the next few weeks, but at least no one else will.
