I think we do not need to have the monitor for the bus no.5. All staffs who take this bus should pay the membership fees. For Khun Yupa (non-member), we should deduct from her payment through payroll by using her timesheet. If needed, I would like to be a volunteer monitor( that means I will collect the fee from outsider who take this bus and I still pay for the membership fee).
Thank you for your consideration.
