Q: Is it totally tacky to dip a half-eaten shrimp back into the cocktail sauce?
A: It’s inappropriate (and unhealthy) to put food you’ve nibbled on back into a communal sauce. Even if you turn the shrimp around to an unbitten side, it’s still wrong. Others might not know the steps you’ve taken trying to keep things sanitary. The correct move is to spoon some sauce onto your own plate, and then dunk as many times as you’d like.
