(I operate a pretty big roller coaster for a ticket run theme park.)

Father: *to his 10 year old* “Shall we ride?”

Son: “We just had lunch.”

Father: “You’re a chicken. I’ll ride it myself!”

Me: “Sir, just so you know, this ride is bumpy and has a lot of quick stops. It isn’t very fun on a full stomach.”

Father: “How would you know? Have you ever tried?”

Me: “No, but I’ve been doing this job for 3 years now.”

Father: “Well, I’ll show you, and I’ll sit in the very back.”

Me: “If you say so; the customer is always right. Have fun!”

(The father boards the ride, and I keep an eye on him. As I predicted, he isn’t going doing so well and is clutching his stomach throughout the ride. When the ride finally jerks to a stop, the puke flies.)

Son: “Dad, I told you not to do it!”
