How would you handle a situation where a paying passenger began to
manhandle the controls?

Karate chop to the throat.

What would you do if a passenger keeps interrupting you during a
single pilot IFR approach into a very busy airport?

Tune him out, either with pilot isolate or just ignoring him.

What would you do if your passengers lit up their marijuana in the
back of a twin?

Ask for some.

Actually, I would land immediately. My plane has no ash trays and smoking is
strictly prohibited by the POH. I would also consider that the plane has had
its value permanently reduced to some extent -- drug sniffing dogs will
alert on the plane for years -- and I would demand compensation.

What would you do if the passenger was so big they kept getting in the
way of control travel?

That would be determined when computing the weight and balance and during
the before takeoff control check.

What would you do if your passenger decided to get out of the airplane
while in flight?

Depends on where he was sitting and whether I felt I could do anything about
it.

These are all real and all have happened to me in my 45 years of
flying. A lot more that I can't think of at the moment.
A pilot was recently faced with it when an 84 year old man decided to
unstrap and get out of the front cockpit of a biplane and plunged to
his death. The pilot was unable to stop him.
What would you do?

He was 88. If you are unable to stop him, then you are unable to stop him.
File a dropped object report.
