Seeing people do it, doesn't mean it is ok. Tyler is a former monorail pilot and bus driver. He was saying it nicely, please don't eat or drink on the bus or monorail. Do people do it, sure. But it doesn't make it right.
Our world has turned into a "the rules don't apply to me" society. Not pointing any fingers at anyone, but come on folks, they ask you not to eat or drink on the transport, so obey the rules.
You can eat right when you get to the park or have something in the room before you go. You can bring creal bars or other granola type bars in your luggage so you have a little something.....
Have a wonderful, rule following trip, everyone!
