would you like some- would you like to have some

We're seated at dinner and I'm passing the salad (or other food, but not drinks).
"Would you like some salad?"
"Would you like to have some salad?" (sometimes)

I'm preparing dinner and am really asking, Should I make a salad (or other food, but not drinks) or not?"
"Would you like salad with dinner?"
"Would you like a salad with dinner?"
"Would you like to have some salad?" (usually)

I'm offering. (usually drinks, not food)
"Would you like a beer?"
"Would you like some tea/some coffee?"
