Consider yourself lucky. Cashiers here will card people buying cigarettes if they look under 26 or something. I'm almost 31 and get carded anytime I go to the liquor store or order a drink with dinner. There are just too many liabilities out there for businesses, servers, and even cashiers. They can face huge fines, most of which are over $500. I don't think anyone making minimum wage wants that on them. Its just the way it is. Carry your ID in your wallet from now on.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
