Meh, refusing service due to age just isn't the same as refusing service based on the way people were born, or when they belong to certain cultural groups (especially people who have a history of being persecuted).
By your logic, people should be upset that the legal smoking age is 18, or that kids of any age should be able to join the military. Toys for tots takes on a whole different meaning!
Let's say I'm selling a RF (Made up product) and the government has mandated that you must be 16 to buy one. Let's futher suppose you, at age 17, and @YmirGF at age 20 come into my store and ask for one and I say "Despite the law, I have decided to discriminate against you based on age as I believe that RFs are dangerous to anyone under 18.4 years old." Would I be violating your civil rights?
