It can take hours to prepare for a date, whether that includes getting dressed and putting on makeup, or going to the gym, or saying affirmations in the mirror, or all of the above. But to ruin a date?! That can take seconds. As uncomfortable as it is to be on a date that goes badly in under a minute, you almost have to admire the efficiency.
1.) From LydiaAgain:
One time a guy leaned over and deeply smelled a lock of my hair within the first couple minutes of our meeting for the first time. I made up an excuse and left
2.) From hakureimu:
On the first (and only) date with a girl. Told her I worked part time and she started bragging about her expensive car and our conversations essentially went nowhere the whole time. I found out later she was fired from her job for stealing from the till.
