In the food delivery services, majority of the food which is being delivered is haram, since supplying haram is considered makruh tahrimi, the ulamah kiram have instructed that the person should give the haram portion of their salary as sadaqah. Therefore, in addition to discharging of the above mentioned sadaqah, one should keep on looking for a new job and as soon as they find a new job, leave the food delivery job.

وَمَنْ حَمَلَ لِذِمِّيٍّخَمْرًا بِأَجْرٍ طَابَ لَهُ) عِنْدَ الْإِمَامِ (وَعِنْدَهُمَا يُكْرَهُ) لَهُ ذَلِكَ لِوُجُودِ الْإِعَانَةِ عَلَى الْمَعْصِيَةِ وَقَدْ صَحَّ أَنَّ النَّبِيَّ - عَلَيْهِ الصَّلَاةُ وَالسَّلَامُ - «لَعَنْ فِي الْخَمْرِ عَشْرًا وَعَدَّ مِنْهَا حَامِلَهَا وَالْمَحْمُولَ إلَيْهِ

{مجمع الأنهر في شرح ملتقى الأبحر}

واللہ اعلم بالصواب
