"If its any of your business:
1. I was away on holiday
2. I had to work
3. I was ill
4. My mum died.
- so what now ?"
I usually miss one every two seasons with illness. 5% empty seats would seem about par in winter cold season. I could missed many more x 5 when connecting trains did not arrive, but we clubbed together to get a taxi. Or very bad weather if cycling when the trains are not running. 800 seats is 2.6% empty.
