Receivables [Abstract]
Insurance Receivable	Insurance ReceivableThe Company's financial statements as of October 31, 2018 include a $7.1 million receivable from insurance carriers for property damage and expenses incurred as a result of Hurricane Florence and Hurricane Michael, net of the applicable self-insured retention and deductibles. The Company's applicable insurance policy includes a $2.5 million self-insured, eroding retention per policy year, which was completely eroded as a result of Hurricane Florence, and additional $250,000 deductibles per occurrence. As a result, the Company's operating results for fiscal 2018 include $2.75 million in charges for damaged property and expenses incurred as a result of Hurricane Florence and $250,000 in charges for damaged property and expenses incurred as a result of Hurricane Michael. Additionally, the Company's operating results for fiscal 2018 include unrecognized lost revenue and reduced margins which were the direct result of the hurricanes, and calculations of those claims are ongoing. Recovery of the lost revenue and reduced margins will be recognized once the calculations of the claims and negotiations with the insurance carriers are complete. The Company will seek reimbursement for all of its insured losses, including the unrecognized lost profits and reduced margins. As of December 18, 2019, the Company has received from its insurance carriers payments totaling approximately $11.3 million related to the Hurricane Florence and Hurricane Michael claims.
