33a Do(p)ing
33d Del (operator) E
There is a difference of opinion regarding the blanked-off area.
SPOT satisfies the Title while Slot fits the vending machine connection.
As I said in an earlier post there is also the hint in the preamble about the omitted letter (P). If it is taken that P is Pennies,
and they 'do not emerge' (from the machine) then SLOT would seem to be the correct one.
