is it ok to use buses within your main town to boost growth?

Hi all

I think not!
Buses shall only be used to transport passengers and mail from other towns to your main town.
If you send buses within your main town around into busstops... i dislike!

But it is not mentioned in the rules, more and more people i see doing it. makes me sad:(

Please comment!

Thanks!

It´s not forbidden and has been called internal service. This meachanics enabled a faster town growth.
