First: If it is a primary part of one’s job and they cannot excuse themselves from sitting or participating in these meetings, there is no sin upon them. They may carry out their work without participating in the drinking activities.
Second: If one can excuse themselves without harming their job or if it is not their primary work, it is not permissible for them to sit with those who drink, as Allāh says: “And when you see those who engage in [offensive] discourse concerning Our verses, then turn away from them” [Al-᾽An῾ām: 68], and “So do not sit after the reminder with the wrongdoing people” [Al-᾽An῾ām: 68].
The matter should be assessed accordingly based on the harm that might result from leaving the gathering compared to the harm of participating. Consideration should be given to the worker’s circumstances, as some are compelled by their situation and the necessities of life can sometimes be pressing. Also, consider the nature of those attending the gathering; it is easier if they are non-Muslims who are not bound by our Shariah compared to if they are Muslims.
Regarding restaurants that serve food but also have a section for alcohol: if the alcohol section is open to the dining area where diners and drinkers are together, it is not permissible to visit. However, if the dining section is separate, it is permissible to sit in the dining section. It does not matter if someone at another table orders what is prohibited for Muslims, such as pork or alcohol, as long as the seating areas are separate.
