It's a big world, so I'm really just focused on the United States perspective for the moment. (Not an entirely familiar culture for me.)

You're out to lunch. Your companion says "that looks delicious". What now?

For a spouse or significant other - even on a first date - I'd shove my plate over and offer a bite. (No, I don't "feed" even a spouse, but that's just me.)

What if it's just a friend? What if it's a co-worker at a casual lunch? Your boss?

Somewhere in there, it ceases to feel "right". Your thoughts?
