I have to get together with a colleague from our Montreal office. My boss said it didn't matter whether I went there or she came to Toronto. I said I'd prefer to go there. I could do it on a Friday and make a weekend of it. It wouldn't cost the company any extra, as the flight would be the same price regardless of whether I flew back on Friday night or Saturday night. Besides, logistically it makes sense to have the meeting there. My boss said no problem.
I figured there was a chance it might not get approved. You know, budget constraints... It is a $300 flight.
My boss's boss, however, approved the trip, just not as planned... She can come here, but I can't go there.
