To quote the great John Smeaton...
This is Scotland, we won't stand for that. We'll set aboot ye.
Sorry but I reckon the big man was right, this wee scrotum of society was causing undue issues for hundreds of others on that train. Each one has the right to get home after having paid their fares. This urchin not only had the audacity not to pay but to become un-necessarily abusive to the conductor. The YT comments go on about the rights of the "lad" and the "big man" surely the conductor has the right to do his job without verbal (or physical) abuse?
