That's up to you as the host. If you're out at a restaurant, people pay their own way for alcoholic beverages. The dollars you received from BraveLove cannot be applied to alcohol. Just let the server know in advance.

If you're hosting in a private residence (either yours or someone else's home), then that's your call. Again, BraveLove dollars cannot be applied to alcohol. If you're conflicted, sometimes it's easier to just say no and not offer it.
