Her pants go missing without her notice

Eric smiled as he walked into the cafe. He had been notified via text about the success of the part of the plan where they got the belt off.
"She's taken off her pants" he read as a new text. Eric knew something Mackenzie couldn't. The SSFC had a man on the inside. More specifically, Mackenzie's male coworker, Chad, who had gotten the view a moment ago, was in SSFC. At the present moment he didn't have the wristband due to job dress code. Now that played into his favor.

While Mackenzie was turned away he nodded to Eric, who hopped into line. Eric made sure to grab a tray as he did so, getting pizza from Chad at the pizza counter where he ordered. Chad relayed his order to Emily, who prepared it and let Mackenzie know she had it. As Mackenzie turned away from the counter, Chad struck. He quickly moved to grab her pants, folded beneath the counter, and slid them beneath Eric's tray as he waited. He moved off just quickly enough to avoid suspicion as Mackenzie turned back.

She came face to face with Eric, though couldn't place exactly where she had seen him before. He looked super familiar. Where do I know this guy from? she thought to herself. The lighting in the lecture hall had been dim, and it became clear to him from her expression that she didn't really recognize him, even though he had made her cum a few weeks ago. On a lark, Eric said "Lookin' good. Could I have your number with this donut and shake?" Mackenzie blushed, aware of her present state. Normally she wouldn't mind a guy asking, she might even be flattered. Something about this guy seemed too familiar and felt off "N-no, sorry" she said timidly before she turned to grab the next shakes from Emily, who had called for her attention, before grabbing a donut for another customer.

"Fair enough" Eric replied, turning away with his tray, whisking her pants off the counter. Holding them beneath the tray subtly, he headed away from the counter. Rounding a pillar and out of her view, he checked the pockets of her pants. Surprisingly, he found them to be empty. He shrugged, figuring he kept her keys and wallet in a purse or jacket and looked around once. In a way, he was almost glad she had turned him down, otherwise he'd probably feel bad about his next move. Seeing no one paying attention to him, all eyes on Mackenzie, as it were, he threw her pants into the trash. Mackenzie wouldn't be finding them today, if ever.

He texted the rest of the SSFC. "Belt and pants out of the way, proceed with the next phase". Whistling, he took a seat at a booth and set his camera up to subtly record Mackenzie at her post. His part in this play finished.. for now.
