Claimant, who was a customer of the debtor and who had purchased a membership in the franchisor of the debtor, filed a proof of claim seeking a refund of his membership fees after the debtor closed the local showroom.  The chapter 7 trustee filed an objection to the claim.  The court found that the trustee did not carry his burden in rebutting the presumptive validity of the proof of claim, but did carry his burden as to the amount of the claim and its priority status.
