When people get old and senile they put plastic bug catchers on the front of their bus. The theory is it protects the stainless and the paint in the front from dings when they follow the car ahead too closely.
Then they drive around with a bus so ugly it makes the dings they would have gotten look like beauty marks.
When they wash their ding free buses they have to clean the plastic which has the clarity of milk, and then they have to lower the plastic down to clean the front of the bus and the back of the plastic. Since they are old they also are retired and have plenty of time to screw around with the plastic bug catcher.
Then they go in the coach and sit on the sofa with its own plastic shield. The crackling of the plastic as they move around keeps them awake, and when they try to get up from the sofa their skin sticks to the plastic and peels off the top layer. (Skin, not plastic)
They also keep the plastic carpet protector on the floor, all of this to keep the bus in pristine condition for their grandchildren who will take it to Panama City on spring break with about 30 of their closest friends who will in one weekend do more damage than 25 years of ownership ever did.
