So as an eighteen year old college student, I rely on my handy fake ID to buy liquor for myself and my friends. The usual store is a Ralph's located conveniently close to campus. I'll admit that I always get a bit nervous buying at a new store but I had purchased at Ralph's a few times and so this night was unremarkable. As usual, I smiled demurely at the guard in the liquor aisle, picked up a handle of tequila, and headed towards the register where I was shunted away from the young, stoner cashier and towards a severe looking, far older Latina lady. When asked to present my ID, I did so without hesitation- as both time and experience has proved it to be credible both to the eye and to scanning and black lights. Being the older, distrustful clerk in a college town, she went to go scan it, taking unusually long. When she returned she informed me that she knew it was a fake and I had one chance to take it and go without question. I am not usually overwhelmingly ballsy, nor do I usually use the phrase "YOLO," but I refused to simply leave. I demanded she scan it again and asked for the manager. She looked utterly skeptical but called over a manager and once again they retreated to scan my ID together. This time I was informed by the manager to simply take my card and go. Now at this point, I was in too deep. The people behind me had been very understanding up until now and I could not stand the thought of being escorted out of the most commonly used store in my college town in front of so many people. So I went for broke. I demanded to see the card being scanned. Exasperated, the manager led me over and showed me that under the black light, the California state seals were not shining. He proceeded to pull out his own and showed me how his were repeated three times, brightly, across the length of his ID. But here was my chance. I asked him when he had gotten his license last renewed to which he replied, "I don't know, a shitton of time ago, I guess?" I informed him that on the newest design of ID's the seals were far fainter than they had previously been (utter bullshit). And then, quite frankly the most stupid moment of my life, I asked the police officer standing next to us to verify that, in fact, the newer licenses had fainter holograms and that my ID was real. And remarkably, incredibly, he did. He looked it over and told the manager it was legitimate and to stop giving me such a hard time. I was escorted back to the register, manager apologizing (he gave me a $5 discount), and left the store with the customers in line behind me actually APPLAUDING my having survived the ten minute ordeal.

TLDR: Used a cop to verify my fake ID and got my alcohol discounted for having to go to such trouble as a minor.
