fuel tap pointing up and i run out of fuel

[undercover]

what a nightmare just took the slip road off the bypass and my ntv650 1997 model cuts out
the fuel tap is pointing up '' on position'' and i am out of fuel

what the hell

the bike used all the petrol in the tank whilst the fuel tap was pointing up '' on position ''
i turned to reserve and there was no bloody fuel and it drained my battery after trying to turn it over 5 times.
had to call RAC who bump started it after me pushing it to the garage and filling up
anybody else had this problem
what the hell caused this or do i forget reserve from now on
