Grocery store ID carding?

I’m 21 years old, but my only form of ID is my expired drivers permit from when I was 16 LOL. I know I wouldn’t be able to use that at a bar or a liquor store, but I feel like every time I’ve been with folks buying alcohol at a grocery store using self checkout, the attendant is usually always super chill. Like I’m of age, I just want a bottle of wine LOL. Like do yall think it will slide? This is in Vermont too btw.
