Dear Developer!
The following problem was found. If there is only one employee but two services, the guest can book for the same time. For example: Monday booking 08:00, work1, worker1. Monday booking 08:00, work2, worker1. This is not good because worker1 can only do one thing at a time. Please fix this bug. You can try this bug on your demo page: https://easy-appointments.net/responsive-single-column-layout/

Best regards,
