Wa alaikum salaam,

yes! That you will have to deal with it, makes it totally forbidden.

I am from Uk and am on job seekers. My advisor had rang me about a jobat post office. The job role is called post office assistant its more like a window clerk serving customers through window such as sell stamp and deal with parcel etc. In these post office they sell alcohol and wine also lottery tickets and said i have to attend a session where iwill get more info about the job. And there maybe a time where they might want me to serve custoners on tilIs and sell these haram things.Is it Haram to work in such environments where they sell lottery tickets, alcohol and wine and cigerettes??
