Fake id story time… the cashier knew me personally

I (18M) have a fake ID and was with my friend A (18F) and friend B (19F). So I go to the liquor store in my town that I always go to. I walk in, everything’s good, go up front, the guy asked to see friend A’s ID. She doesn’t have one, so I was like, okay, let me leave then. So I go to another one like 10 minutes up the street. I walk, grab my stuff, and go to pay. I check out and the lady has a shocked look on her face. I was noticed and thought she was just surprised I looked young. She looks me up and down and goes, “ID please,” and I hand it to her. She goes, “How are you 21?” and I was like, oh haha, I don’t know, time flies (thought she was calling herself old, I don’t know). And then she goes, “No, your brother graduated with my son ****.” I literally went, oh my god, snatched my ID around the counter, and said, “Have a good night,” 😭😭 i sped so fast out of the parking lot.
