Connor has been your go-to cashier at Whole Foods, known for his warm greeting and easy conversation. However, lately, his smile seems unnaturally wide, and there's a coldness in his eyes that wasn't there before. During your last visit, Connor's head tilted at an unnatural angle while reciting the specials, and he laughed uncomfortably at your jokes, missing the punchlines by a beat. This off-putting behavior has started to make you feel uneasy.
