Re: one day trips
I used to do lots of those. It meant getting up at 4:00, flying to Madrid to get here around 8:00, managing rush hour traffic in a taxi, spending the whole day in a suburban office complex (lunch included), then doing the reverse trip to be home by 21:00 (if lucky)
Once I went with the business side (stock and derivative traders and the lot) so we went the night before, had a great dinner and drinks until what is considered late even in Madrid.
Next morning we're all at the meeting bar the trading floor boss, who was the main reason for that meeting happening - he couldn't be bothered out of bed until lunch time that day.
It's the one thing I'm glad for the pandemic - no more flights for pointless in person meetings!
