Assalaamu Alaikum
Thats the case with alot of Muslim's these days

Insha Allah maybe you should explain to them the danger of selling Alcohol.
Narrated Anas ibn Malik "Allah's Messenger cursed ten people in connection with wine:
the wine-presser,
the one who has it pressed,
the one who drinks it,
the one who conveys it,
the one to whom it is conveyed,
the one who serves it,
the one who sells it,
the one who benefits from the price paid for it,
the one who buys it,
and the one for whom it is bought."
Tirmidhi and Ibn Majah transmitted it.
[Al-Tirmidhi #2776]

According to a hadeeth narrated by Jaabir, the Prophet (pecace and blessings of Allaah be upon him) said: “Whoever believes in Allaah and the Last Day, let him not sit at a table where wine is being served.” (Narrated by al-Tirmidhi, al-Adab, 2725; classed as hasan by al-Albaani in Saheeh Sunan al-Tirmidhi, 2246). The commentator on the hadeeth said: even if he does not drink with them, it is as if he is approving of their evil action.

Question :
Is it permissible to eat at restaurants where alcohol is served?.
Answer :
Praise be to Allaah.
If it is possible to eat elsewhere then it is not permissible to eat at these places, because that involves cooperating with them in sin and transgression, which Allaah has forbidden. If it is not possible to eat elsewhere then it is permissible to eat there in cases of necessity, because Allaah says (interpretation of the meaning):
“and has not laid upon you in religion any hardship”
[al-Hajj 22:78]
“Allaah burdens not a person beyond his scope”
[al-Baqarah 2:286]
But he should not eat or drink anything except that which Allaah has permitted.
