KEY POINTS

When asking about appetizers, I ask if they'd like me to get them a specific item (or two).

I ask guests if they would like an 'appetizer' because:
'Appetizer' is an undefined, vague label that holds no inherent appeal.
Calamari (for example) sounds more appetizing than the word appetizer.

Imagine you're a guest. What are you more likely to respond with yes to?
Do you want an appetizer?
OR
Would you like me to get you some calamari or focaccia bread (or some other delicious-sounding menu item)?

*I'm not trying to fool anyone, it's just a more agreeable way of framing the question.
