is this a sin or bad ?

so i got invited to a baby shower but for some reason it got moved to a church, weird. But it’s on saturday . The thing is i wanna drink before i go because i get more social and talk a lot. And it’s saturday so. But the thing is it’s at a church? so im confused . Church won’t be in session but jt willl be open in another building but not in the church , ( i don’t think). So will it be alittle bad if i go alittle buzzed to the baby shower ? im just gonna drink until i feel a buzz anyway, I AM NOT GOING TO DRINK IN THE CHURCH OR WHEREVER ITS AT, im drinking before at my house. But i’m saying will god be mad at me for being “ buzzed” around his building ? im overage so. lol
