Is it normal for Swedish long-distance bus/coach drivers not to count for missing passengers after rest stops?

Back in 2001 or 2002 I was travelling by coach in Sweden because it was cheaper than the train.

There was a break for lunch and I believe it was 15 minutes. I didn't have a watch and didn't spot a clock in the rest stop which was so enormous that the other passengers dispersed and I couldn't track them. Anyway when I finished my sandwich I looked around the building and my bus was gone with my luggage on it!

Is this normal for Sweden? Or did I just have a particularly hardline bus company or a particularly grumpy driver?

I've taken long distance buses in a dozen or more countries, rich and poor, and never came across drivers leaving after a break without some kind of minimal check that the passengers were on board.
