The management pilot should be written up for use of a mobile phone whilst in control of an aircraft. Was he taxiing it at the time?
The Captain taxiing slowly could have had any number of reasons he was taxiing slow. It seems to me that the management pilot is looking to kiss some a$$ to try and either get a promotion or a pay rise.
