It wasn't so tragic holidays but with my wife we were on Crete. We wanted to visit a lot of places so we rent a car. First two days were good and we traveled a lot but on the third day they started strike in whole Greece and the gas stations were closed. Unfortunately we didn't know that at the beginning of that day and we traveled 50 miles from our hotel. We had a lot of troubles but after two hours we found an open gas station. I also have an argue with a car renting company but it's a story for another time.
