A round lid will not fall in the hole, in any way you put it. The plant here may mean manufacturing plant. I will select the upper berth as it will not be a disturbance to me as well as other passengers. I will offer menu for living only because the dead will not eat anything as they have no body and hence nobody.
A round manhole cover cannot fall through its circular opening, whereas a square manhole cover could fall in if it were inserted diagonally in the hole. Circular covers don't need to be rotated or precisely aligned when placing them on the opening. A round manhole cover is easily moved and rolled.
