Do they have a trainer that goes out with them on some of their first trips? If he was just that bad I can't imagine him getting past that stage. But the more and more I go over this in my mind I think he was inebriated or as someone said above was maybe having a medical issue. Perhaps he was diabetic or something and had low blood sugar. I just can't believe an inebriated cast member could be allowed to get on a safari truck. Just like I wouldn't believe it if there was an inebriated bus, boat, monorail or tram driver.
Side note - I did have a tram announcer say damn one time going to the magic kingdom. Just sort of rolled off his tongue. I don't think he was inebriated just one of those that slips out as he seemed to be going off script a bit while we were waiting for other tram traffic to clear.
