Alhumdulillah I'm doing well
Praying for you best health and prosperous life.
You are not allowed to sell alcohol.Either try to find work where alcohol is not involved or find any other position in supermarket where you will not be involved in this.
Inshallah you will be able to find rizqe halal and pure as quran said
Whoever is careful of his duty to Allah , Allah will open the new outlets and grant him sustenance from the place he never think.
(Sura Talaq ayah 2,3 )
