Do people dread cocktail parties because of what they do to their weight or see them as free food now?

Funny. I'm not sure what you're asking. Some people dread cocktail parties and some don't. For those who do dread cocktail parties I would imagine that the reasons are varied. Btw, people can manage what they eat and drink on their own. The presence of free food and drink does not force anyone to eat or drink it.
