Has anyone ever run their car down to 0 miles on the BC?

I got into a situation at work at the weekend where the nearest 24hr petrol station was 45 miles away! it was 1am so really i had no option but to stick it in 6th and cruise at 50 and see how far i got. 15 miles on the 0 miles BC suggestion. I know it's not good for the car to run it on such a low amount of fuel and the consequences could have been disastrous it it had run dry but has anyone else suffered similar?
