I wonder if promoting a business only works if a lot of akcohol is involved. I hope your goal is achieved and they signed or whatever the occasion was meant for.
I would say _ cheers_ onto your next trip I hope you won't suffer from hangovers 24/7 if you are super succesful!
Fortunately, the hangover was resolved in the afternoon. Drinking alcohol is not essential in promoting the business, but it seems necessary to some extent to drink together as a celebration after an important business discussion. I hope the new business will be successful. :)
Good to hear you could travel back without a headache.
Stay healthy!
