How can a Muslim woman, while observing the full hijab that covers her face and hands, attend to her necessary needs such as drinking and eating in public places filled with men who are not her mahram?

A veiled Muslim woman has several options for eating and drinking without uncovering her face in front of non-mahram (definition) men. These include: letting her head covering fall over her face and putting her hand underneath it, or turning her back to non-mahram men and facing a wall. If she is unable to do so, it is permissible for her to uncover her face out of necessity, such as drinking when thirsty. She should avoid sitting in open restaurant halls unless absolutely necessary, as they often contain religious prohibitions.
