I disagree. Where are yall going where folks are scared to eat food at an event designed to do so? Is that pie? Oh no much rather look than eat even though clearly it's there to be eaten and everyone is eating.

If anything if you're going to take a slice do so because you want gurantee you get a slice not because "oh no people are scared to eat food at a food event." Otherwise it's actually considered rude in many folk's households to show up with an incomplete dish you've eaten off of.
