I avoid the alcohol aisle as it has nothing to offer since im sober
I hear you about handling the alcohol at the checkout and i suggest 2 things
1.is it possible to ask your boss to work stockroom or off the checkout
2.if that is not possible and you intend to stay then i suggest remembering that we & all of us are here for you after work your not alone i can understand
My other suggestion is accepting just for today a mere 24h that together me you & all your friends here can stay sober
Deal ?
