A potential supplier invited me to have a drink at a place I’d never been to before. I usually don’t pay so I just agreed — 30 seconds from the office, and just half an hour commitment, no big.
Turns out it was a very upscale restaurant. Not just a drink, but a full 4 course dinner with 3 bottles that he’d brought along to show me.
3 hours later, I’m very full indeed.
