How do you respond to someone who cancels last minute?
I'm sorry to hear that you won't be able to make it tonight. I was really looking forward to getting together. I've got so much going on these days that it would've been helpful had you reached out sooner, but I understand these things happen. Hope we can reschedule this!
Is it bad to cancel date last minute? If you just hint that you are not going to be there and don't directly tell the person, then it is rude. If you cancel because you have something “better to do or you got a chance for different plans, then it is rude. If an emergency came up, then it is not rude.
