I believe the answer is:
owed
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">had bills to pay</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for owed that I've seen before include "In debt to" , "Was indebted" , "(Sum) due for payment" , "Had an obligation to pay" , "Had a duty to pay" .)
