Go to the car show every year.... Every year the convention center staff does something stupid to make me ask why I go. This year we get hand stamped for reentry. Get a bite to eat. Return to re-enter and are rudely told we can't as they stopped selling tickets. What? Ask how to get to the train and the staff says "walk around the building outside". Typical staff with no customer service skills.
