A warning should have been enough.
I got thrown out of the Sprint Labs in Burlingame.
Tokyo was pressing Dallas to press me to press on the Sprint guys to get moving on their acceptance testing (major in-service millisecond outage upgrade to ATM long haul backbone network hardware/software).
I came back from lunch, and said something like "Ok guys, it's showtime!" in my best Beetlejuice impersonation.
Got a call from my manager, checked out of the Embassy, window seat to Dallas., an evening with my gear.
Some wiser heads prevailed, as I had been the nursemaid for the project in Tokyo and was the only one that knew what was going on in English.
Very next day, fly back to Burlingame. "Hi guys!".
I never found out what really happened.
