****y Management Bossa Tyger Falls

So my son and a friend went for drinks at Bossa Tyger Falls. Whilst enjoying their drinks my sons friend asked if they can assist him with charging his cell phone. They gladly assisted him and placed it on charge. After n while he asked to have his phone back but there was no phone . He called the manager and they look at the footage. According to the manager you can see the phone is put on charge but you cannot see who took it. So when they asked how is it possible for the phone to get taken out of the office ,the manger got rude and unresponsive .
