How often do you think the people who work at amusement parks during the halloween horror events get hit?

To explain: I want to go back to Hallowscream at Busch Gardens, but my husband doesn't want to take me back. One time a few years ago my husband and I went to Hallowscream and at 3am (after a few drinks), while we were heading to the gate to leave, a guy jumped out (I didn't see him) and screamed 2 inches away from my ear. I instinctively punched him. My husband swears this isn't the norm. I figure it probably happens to these people pretty often. What do you think?
