A question from a drinker

Someone ask this Question.
Tell me what you think?

If someone does this, what will happen?
If they got drunk for the first time one night (not overly drunk, but drunk) and then the exact next morning, they drink two double or single shots of straight high quality vodka, will they get drunk much more easily? Is the liquor from last night gonna affect how drunk they get? Will they get drunk more easily?
