I "managed to get bullied"? No, I put the pen down and asked him to make a phone call and ensure it will be approved, whatever he thinks that means. Somehow the question of "it getting approved" was resolved without him ever making that phone call.
This is a classic car salesman tactic. The idea is that a buyer that's completed paperwork will be more likely to agree to a last minute price increase "because my manager won't let me sell it for $X". It's a total bullshit move. It's so common it's even mentioned in the book Influence: The Psychology of Persuasion.
He probably thinks I bullied him.
