Agree wholeheartedly with your rule. Mad how little self-respect is involved in an adult running for a bus or train. Just be late, it’s fine. I’ll allow an exception for last trains, or if you’re on your way somewhere important, like a job interview, etc.
I’d go further than the no running rule. I think travelling on busses particular is a no-go if you’re a fully-functioning adult. Now obviously some people have no choice, fair play, i wouldn’t judge, but it’s beyond me that people on good incomes do it. I’ll be honest, i like a train journey, so my rule to them only applies during rush hours, etc. For coaches see busses. I think people on reasonable salaries have a social responsibility not to clog up public transport.
Secondly, and completely unrelated, there are only certain things i’ll be seen carrying stuff in. Rucksacks and backpacks are an absolute no. Flatly refuse to give anyone the impression that i’m anything but a chilled-out entertainer. Imagine bumping into someone whilst you’re stuffing your rucksack with frozen peas. Fuck that.
