"Jeremy" here.
To be honest: I have no clue, what our service manager told our customer.
I just recall me running out of the DC and through the building to alarm our team lead and the service manager.
No arguing, within seconds people dropped everything they were working on and started sending out emergency alerts. it even went out via the PA!
(That only happened once after that: We got the "all clear" after a bomb threat, due to an American VIP visiting us to present her biography)
I tend to think the arguing and discussing futilities started a few years later, where everybody started "managing" instead of working.
