I work in a restaurant where everything is halal, except for the alcohol. Occasionally I serve this to the customer, should I look for another job, as this is my only source of income?

If presently this is your only source of income, you will be excused for
working there. If possible, you should avoid serving alcohol and search for
an alternative income.
