Had an employee of mine who wanted to try sushi, and thought the green stuff was avocado. Promptly smeared the whole 1/2 golfball sized wad onto a single piece of California roll (he also had raw fish issues) and pop it into his mouth before we could stop him. I've never seen anybody turn that shade of red before, eyes watering like he'd been pepper-sprayed, gasping like he'd been gassed. Once we determined he was not going to go into respiratory arrest, it was funny.
