We saw someone get kicked off a Steel Vengeance train with restraints already locked because he had a phone in his pocket. This happened right behind us, ride op was about to lower his restraint, saw phone, made him get out of the train. When our train came back, he was still sitting behind the exit gates, so we're not sure if he was waiting for someone else or they were going to let him back on at some point. Also saw multiple people with phones in the queue one evening, even using them where ride ops could certainly see them.
On this same trip we also saw them a Maverick train backed off the lift hill, a ride op walked over to the train and then took a phone from someone in the very first row. Also had a ride op for one of the woodies on the trip yell at kids (teenagers) for touching the railings while the train was ascending the lift hill. I did laugh at one of them yelling out, "The government is watching us!"
