Obviously it wasn't Kurt's patience being tested but his faith in the world and sentient beings because he'd never met anyone, human or mutant, who was quite so infuriating as Calvin Rankin. It was like his sole lot in life, no matter what was going on around him, was to be a complete scheissekopf. Rolling his own eyes, Kurt followed Calvin out of the room and heaved another sigh when he slung yet another insult at Rogue, who wasn't even here to defend herself (though Kurt was sure his sassy schwester could most definitely manage a far better defense than he could). "Calvin," he said, his voice a warning. He was certainly starting to regret this decision.
Kurt was forced to resist another urge- this one to rip the uniform right out of the ungrateful man's hands- and crossed his arms while he glared at Calvin. "Perhaps you have misunderstood me. I am giving you an opportunity and asking for your help, not insulting you. There's no need to act this way."
