What is the ruling on selling food at resorts, and is its profit lawful?

Selling halal food and drinks in resorts is permissible. However, being present in mixed-gender resorts where nudity and ostentatious display of adornments are prevalent is dangerous for a Muslim, as one will not be safe from temptation (fitna). The Sharia came to block the doors to temptation, thus prohibiting looking at 'awrah (parts of the body that must be covered) and prohibiting seclusion with a non-mahram woman because it is a path to indecency. Whoever places himself in such resorts has opened a wide door to temptation for himself. Ibn al-Hajj mentioned the harms of trading with women who display their adornments to men, emphasizing the necessity of complete caution, and if one cannot maintain it, then he should leave work in such places.
