Some of the employees at grocery stores (e.g., cashiers) have to deal with wine among the customers other goods during checkout, which sometimes requires handling it and giving it to the customer or only receiving its price. Is that permissible?
It is permissible to work [at a grocery store] but it is not permissible to handle wine or serve it to anyone, even if they consider it lawful to drink. As for the cost of wine, it is permissible for the employee to receive the payment if the two parties to the sale are non-Muslims.
Moreover, it is not permissible for a Muslim to be hired to sell or serve wine or wash its utensils in preparation for drinking. Similarly, it is not allowed for them to take the wages for this work because it is prohibited and not justified by dire need for money.
God says, “Whoever is wary of Allah, He shall make for him a way out and provide for him from whence he does not count upon. And whoever puts his trust in Allah, He will suffice him.” ِThe Holy Prophet (pbuh&hp) is reported to have said, “No soul will die before receiving its allotted sustenance in full, so fear Allah and seek [your livelihood] appropriately, and do not let delay in sustenance make you seek it by means of disobeying Allah.”
