I never delete a MSC after taking the time to sign up. I don't understand if there are no shops for someone your age or if the only shops require a higher rating? If it is the rating, just keep applying. If other shoppers are out of rotation they will eventually take a chance on you. If the age restricted shops stay on the board with no takers, and you are within 10 years, apply. If the age can be waived they may assign you. The worst thing that can happen is you don't get the shop.
For several years they only had one gas station shop near me. Eventually they added a garden store which I loved plus it had a decent reimbursement and great bonuses. Alas, there was good and bad news about the store. The good news is they were bought out and are now locally owned again. The bad news is they are no longer shopped. It was good while it lasted.
Equal rights for others does not mean fewer rights for you. It's not pie.
