Job References for Low Skill Job

I am a college student trying to find employment over the summer. One job I am highly considering is stocking at a local outlet mall. Most of the stores in this mall highly recommend three references, to the point where it is practically required. I have one prior employer who I know would strongly vouch for me (camp director), however I have only had one other past employer besides them, and we are not on great terms due to the high turnover rate of that job (Busboy). I feel that this is not a position that requires too many references, but I do not want to be overlooked automatically because I don't have enough references. Any recommendations or advice?
