Waitressnya less observant and do not want to ask down. I bought a voucher 2 times but I could use it 1 time. Even though the next day I returned to batam. Just take a walk to the field. Finally loss. Where is the room for a capacity of 9 people. So I pay 2 vouchers using 1 voucher. Because of negligence the waitress said she could use 2 vouchers in 1 day
