Question of age

So ALC and the NSLC both randomly put up pictures questioning you if the people pictured in these photos are of age.

Now sure they always post at the bottom which of them are of age and who of them are not of age.

Now both companies always state that when in doubt always ask for identification of the person wanting to be served. If no ID and or not of age then they are not to be served.

So my question is why is it that they put the ages of these people up for if you are being asked if they are of age then they should be asked for their ID to purchase the item in question.

The fines from both of the respectful agencies is a large one and most companies now are no longer covering any part of the fine because it is on the worker to make sure they are doing what they are legally required to do.
