Actually, guys, I think it's a valid question. If his job includes a lot of business networking with non-muslims, eg. westerners, etc. he would need to buy as gifts, etc. He won't drink it cos it's haram for muslims.

I just found out - there's a quota for the amount a license holder is allowed to buy per month. So it stands to reason that some people would need to have that licence for business (not personal) purposes.
