The road to love is paved with disappointing dates. But even if a date doesn't live up to your expectations, social norms dictate that you stick it out until the end. Unless things are really bad, in which case, social norms go out the window (and you might, too, if that's the easiest exit).
In a popular Reddit thread, someone asked: "People who have walked out in the middle of a date, what happened?"
1.) From ohkimma:
He said 'I normally dont really date girls that I dont find attractive so feel special.'
2.) From Minskin:
I walked out even before the date started because my date brought his friend with him. They arrived in a car and asked me to jump in.
