פירוש על עבודה זרה 122:9

According to R. Judah, R. Shimon b. Elazar is more lenient. According to the first opinion, the non-Jew who owns the wine might open up the jug even if it is in the domain of another non-Jew. He might say to his fellow, “If you don’t tell the Jew that I opened the wine kept in your domain, I won’t tell on you in in a similar situation.” But R. Shimon says we are not concerned about such collusion. If the wine is in the domain of another non-Jew the non-Jew who owns it will not open it.
