What is the ruling on working in a shop owned and frequented by a person who drinks alcohol, given that the worker is not compelled to work, and there is no direct interaction between him and the owner, except that he saw him drinking alcohol in the shop?

The mere fact that the shop owner drinks alcohol or commits reprehensible acts does not affect the work, as long as the work itself is free from Sharia prohibitions. However, a woman should not work outside her home unless there is a need, while adhering to Sharia guidelines. Working with someone who drinks alcohol in the shop poses a risk to her. If she is not compelled to work, it is better for her to stay in her home.
