- QUESTION 1 The OMCA club operations When members join OMCA health club, they pay a fee for a certain length of time. Most memberships are for 1 year, but memberships for short periods are available. Due to various promotions throughout the year, it is common for members to pay different amounts for the same length of membership.

Full members have access to all activities. Limited members are restricted to activities they have selected, but they can participate in other activities by paying a usage fee. All members have charge privileges. Charges for merchandise and services are recorded on a charge slip, which is signed by the member. At the end of each day, cash sales and charges are entered into the BumbleBee accounting software, which runs on a computer workstation at each location. Daily cash receipts are deposited in a local bank and credited to the corporate Personal Trainer account.
