Dinner with my English Boss and five Japanese senior managers. He liked to order the best Rioja, unfortunately I like to drink it.
At some point during the inevitable joke round, I decided to up the ante and told the most appalling joke, that I won't repeat.
As the tumbleweed rolled past, I knew I'd cocked this up big time. The following day he let me know what he thought of me and parked it there. I reckon in today's climate I'd have been sacked.
Hopefully I learned about diplomacy from that.
