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.
Usually when someone is feeling overwhelmed and anxious, they will want to avoid what is causing them to feel that way. That would be the time that you would come up with an excuse to not go to happy hour and you will back out of the plans last minute.
People who continually cancel plans at the last minute, also known as social-zappers, tend to have dark personality traits such as Machiavellianism and narcissism, according to a new study.
