Hmmmm, can of worms this one isn't it.

If the bus was running on time I'd say fair enough... how long does it take to stop the bus and gently kick a frog out of the way?

I'm not going to get into a debate about being 20 minutes late, if I was on the bus and it had made me late for work I'd probably be bright red and be demanding froggy blood but at the same time if you're 20 minutes late is a 30 second frog stop going to make a lot of difference?

The main can of worms is who says that you being on time for a job interview is as or more important than a frog's life?

I do seeing as we are talking about a person's livelyhood versus a frog's life but no doubt others will disagree. Everybody is entitled to their own code of ethics though Bilbo and you shouldn't call them pathetic for following them.
