What does Deuteronomy 23:24 allow you to do in your neighbor's vineyard?

Answer: Eat grapes, but fill no basket

"You may eat your fill of grapes, but you must not put any in your basket"; in a grainfield you could pick by hand but not use a sickle.

“When you enter your neighbor’s vineyard, you may eat your fill of grapes, but you must not put any in your basket. When you enter your neighbor’s grainfield, you may pluck the heads of grain with your hand, but you must not put a sickle to your neighbor’s grain.”— Deuteronomy 23:24-25 (BSB)
