I think the whole story and incident sounds overblown to me. A cashier takes the letter of the policy instead of the intent of the policy. I wonder if the sale would have proceeded if the daughter had had an ID so the cashier could see that it was in fact the guy's daughter. I can kind of see how a cashier afraid to sell something (be it alcohol or tobacco) that could be traced to a minor could question this situation given ways some teens will attempt to circumvent the age limits.
