So I have a story for this, one I'm not proud of mind you, but it happened. One time in a lush store they had these bath bombs that were literally modeled to look like cupcakes, I remarked that they almost looked edible. A STORE EMPLOYEE replied with this.
SE: They are edible.
Me: what? No they're not
SE: oh yeah they're totally edible go ahead and take a bite
Me: wait really?
SE: yeah!
So I take a bite of the cupcake looking thing and immediately the bitter ass taste of soap fills my senses, my eyes are watering and I spit it out into the trash. I kid you not this was like a punch in the face, I was sweating, I felt a huge headache coming on and my nose was on fire. Again I'm not really proud of this but in my defence, I was a dumbass teenager and someone who I reasonably thought I could trust told me something to mess with me and I took the bait.
The employee was nowhere to be seen after that, obviously he saw my gullible ass actually did it and got out of there with a pep in his step and a smile on his face. As for me, I had a pounding headache and slightly lavender scented breath for the rest of that day.
