Reference for Bava Batra 114:11

ואי בעית אימא הא והא דליכא ינוקא ולא קשיא הא דאיכא שמעא הא דליכא שמעא

— There is no contradiction. In one case [we suppose] there is a child at the table,<span class="x" onmousemove="('comment',' And then it should be outside, because otherwise the child may play with it and upset the table. ');">²¹</span> and in the other that there is no child. Or if you like I can say [that in both cases [we suppose] there is no child, and still there is no contradiction: in one case [we suppose] there is a waiter at table<span class="x" onmousemove="('comment',' And it should be inside, because if it is outside, it may get in his way. ');">²²</span>
