Well that's a legitimate concern. Me personally I would have at least tried to move the doctors appointment if possible. But sometimes it's hard to rebook and then if you have a new job might not be able to get time off. So I agree its a conundrum if they can't get you in again before the potential start date of new job.

But that's capitalism; not really anybody's fault who you might have been in a position to punish by losing it at them. I'd rather get your frustrations at me than towards the workers at the desk.

Sounds like it worked out in the end schedule wise. Hope everything else goes in a good way.
