His wife, Joanna Hoffman, saw the same thing when she accompanied Jobs to Europe a few months after the Macintosh was launched.
"He was just completely obnoxious and thinking he could get away with anything," she recalled.
In Paris she had arranged a formal dinner with French software developers,
but Jobs suddenly decided he didn't want to go.
Instead he shut the car door on Hoffman and told her he was going to see the poster artist Folon instead.
"The developers were so pissed off they wouldn't shake our hands," she said.
In Italy, he took an instant dislike to Apple's general manager,
a soft rotund guy who had come from a conventional business.
Jobs told him bluntly that he was not impressed with his team or his sales strategy.
"You don't deserve to be able to sell the Mac," Jobs said coldly.
But that was mild compared to his reaction to the restaurant the hapless manager had chosen.
Jobs demanded a vegan meal, but the waiter very elaborately proceeded to dish out a sauce filled with sour cream.
Jobs got so nasty that Hoffman had to threaten him.
She whispered that if he didn't calm down, she was going to pour her hot coffee on his lap.
The most substantive disagreements Jobs had on the European trip concerned sales forecasts.
Using his reality distortion field, Jobs was always pushing his team to come up with higher projections.
He kept threatening the European managers that he wouldn't give them any allocations unless they projected bigger forecasts.
They insisted on being realistic, and Hoffmann had to referee.
"By the end of the trip, my whole body was shaking uncontrollably," Hoffman recalled.
It was on this trip that Jobs first got to know Jean-Louis Gassee, Apple's manager in France.
Gassee was among the few to stand up successfully to Jobs on the trip.
"He has his own way with the truth," Gassee later remarked.
"The only way to deal with him was to out-bully him."
When Jobs made his usual threat about cutting down on France's allocations if Gassee didn't jack up sales projections, Gassee got angry.
"I remember grabbing his lapel and telling him to stop, and then he backed down.
I used to be an angry man myself. I am a recovering assaholic. So I could recognize that in Steve."
Gassee was impressed, however, at how Jobs could turn on the charm when he wanted to.
Francois Mitterrand had been preaching the gospel of informatique pour tous—computing for all
and various academic experts in technology, such as Marvin Minsky and Nicholas Negroponte, came over to sing in the choir.
Jobs gave a talk to the group at the Hotel Bristol
and painted a picture of how France could move ahead if it put computers in all of its schools.
Paris also brought out the romantic in him.
Both Gassee and Negroponte tell tales of him pining over women while there.
