Well, there are completely unnecessary slow moving lines due to incompetent park operations. Yes, Kumali, I'm talking about you! :evil:
Then there's the slowest queue line of all time due to a technical nightmare of a coaster - Maximum RPM at Hard Rock Park. It took 2+ hours for around 60 people to ride & they even hired a karaoke singer to keep guests entertained while waiting in line. It was beyond bad.
