Why I cannot update Current operation mode and Senior hours for a business ?

You can update Current operation mode and Senior hours only for a business which is not registered with Q Waits.

A business which is registered with Q Waits , has the privilege to update its Current operation mode and Senior hours and it won't allow its customers to do that. As a customer if you cannot update the current operation mode and senior hours, it means you are viewing a more realistic information which has been provided by the business itself.
