Do they offer a to go box? Not carry out ! Im talking bout if a person has paid and has to leave before they finished or if they just want to carry the rest if their food home!?

If you've already paid you can take what is left on your table that you have not eaten home with you. You cannot go back to buffet and get more to take hone

You don't walk out with free food. If you leave with food it sold by weight. If they didn't charge by weight people with load up a plate and take it home for free.

Yes

They go by weight. If you want to leave before you're finished, they weigh your vox and charge you accordingly,

I don't believe so
