I really don't want to be dead, so I think this would come as a pleasant suprise. I'd ask for explanation. Then I'd need time to process that none of it was real and to adjust to the real world. The life I lived in the simulation would change me as a person, hopefully for the better.
Is there an option to ask them to put it back on? Would I then have knowledge of the simulation?
In inception, Mal is driven to madness when she does not know what reality is anymore. Being able to put it back on, and then having knowledge of the simulation would have a similar effect I think.
Being able to put it back on would allow you to essentially cheat death hundreds of thousands of times (assuming the sim takes 1 hour).
Doesn't really matter though, as I've never been to a Chuck E. Cheese, so I would not be able to answer any survey questions.
