feeding people

Q: A couple has done nikah and Rukhsati will be a few months later. The parents want to have a function in a hall and feed the guests to let their daughter go with her husband. After alot of insisting they are not doing that and now they are letting the husband take the daughter directly from the house without any function. The girl's side would like to feed their guests. The groom is totally against this. Can the parents feed their guests with another intention and not for the rukhsati?

Q: I have heard that by feeding 60 people (friends/family), this action blesses a new business/home. Is this correct? Or do you know of any other Islamic ruling to support how to obtain blessing/ baraqa for a new business?

Q: Food prepared and distributed as a charity or food bought at a hotel and distributed as charity, which is dearer to Allah (Ta'ala)?
