Is it permissible to sit at a table that includes non-Muslims, on which there are forbidden things such as alcohol and pork, provided one does not eat from it?

It is forbidden to sit in places where sins are committed, such as drinking alcohol and listening to music, unless a Muslim is able to denounce it, in which case there is no harm. However, if the place is predominantly frequented by non-Muslims and the Muslim cannot find another place, and their table is separate, then there is no harm upon them.
