Brine and vinegar and fish brine and oil and honey are exempt from [the restrictions against] exposed liquids, but Rabbi Shimon forbids them. Said Rabbi Shimon, "I saw a snake drinking brine in Sidon." The [Sages] said to him, "That snake was a fool (alt., crazy), and we don't bring proofs from fools" (cf. Shabbat 104b:5).
