Everyone was sitting, and drinks were served:
A honest person would say that the glass is half full. It has beer, soda, bubbles, bubbly, whiskey, gin, tonic, hard drinks, soft drinks blah blah blah. We can fill up the glass, and maybe then drink.
A smart person would say that the glass is half full, half empty. It has beer, soda, bubbles, whiskey, and I am a non-alcoholic with allergy to any drink that makes me intoxicated and you judge me. So I will pass.
A management consultant would say since you have called me last moment, and assigned me a task that requires Wine, whining, and dining with you, 'The glass is twice too big' 'I will drink slowly' 'I will hear you'. You talk. You whine, and I will sign.
