No it happened to me once i was in USA in my student era. It was late night and i was working in the university hall which was just vacant at night becasue it was snowy outside. There was snow outside the campus. A (student) girl came and told me that she is very hungry, i never gave a second thought but said didn't you go to the cafe' nearby. She said "No" and said that she is waiting. I still was not understanding. She said come i will drop you at your home. Then i got little afraid and packed my laptop and walked as fast as i could.....
