Did he manage to cast his phone screen to the projector so you saw that rather than the Wicker Man burst into flames?!
Technically I just saw it was Gmail, but one look at the man and you could tell exactly what he was emailing.
Phones have become a pet peeve of mine at Alton towers. Three separate groups walked through hex with their phone torches on last time I rode that. Walked right past staff who didn't ask them to turn it off.
Not to mention the number of times people whip them out on rides and I have to worry about a potential block of metal to the face.
