Nearly ran out of gas

I was meeting Zip in Chasmonaem yesterday after work, I noticed that my gas tank was basically empty, so I stopped at the first gas station that I saw and they told me that they don't accept foreign credit cards. So i drove on, I got on the Ayaalon in Tel Aviv, my tank was down to two bars, I got off the highway twice and drove around and couldn't find a gas station. I got back on the highway, now it was highway 1, at this point my final bar was blinking. I came up to an exit towards Rishon Ltzion, I got off, and drove for a while, and didn't see any gas stations. I had a feeling that I couldn't turn around and get back on the highway without running out of gas, my best bet was to continue. At a red light I asked someone if he knew where the next gas station was and he said he was pretty sure that it was 2 KM ahead of us, I hoped that I would it. Thankfully he was right I made it it to the gas station, I coasted part of teh time, went into neutral at all red lights, but I made it.
The question is, what would I have done had a I run out gas? Has that happened to any of you here? I did it once in Southfield but I was still on Fairfax when it happened, so it wasn't a big deal.
