What is the ruling on working in a fast-food restaurant on a beach, considering the temptations present there?

Working in fast-food restaurants is permissible in principle, as long as it does not involve anything forbidden. However, it becomes unlawful if it leads to religious temptation (fitna) or to living with and accepting evil deeds, based on the Almighty's saying: "And He has already revealed to you in the Book that when you hear the verses of Allah being disbelieved in and ridiculed, do not sit with them until they enter into another conversation. Indeed, you would then be like them. Indeed, Allah will gather the hypocrites and disbelievers in Hell all together."
