Do they 100% always ask for I.D when buying alcohol? Everyone on the Internet says different things, some say waiters/waitresses check but don't do the math because it gets them a bigger tip for letting it slip, some say clerks always look and are strict for I.D. The majority of you people here being American and somewhat underage, do they? If so, where does a man get his damn beer from? The age limit is 18 in New Zealand.
