cliffy didn't get conned. That's how things are in "upscale" nightclubs in JB.
The 10 hours booking fee does not include anything. 10 hours doesn't necessarily mean 10 hours in full. That time period ends when the nightclub closes. Any left over hours are like a tip.
It also doesn't include any action within that 10 hours; unless all these are clearly agreed upon with the mamasan.
Speaking of different rules, there are even some differences in how things work in KL, Penang and JB. In Penang, I think the "hour" is less than 60 minutes.
