As far as i know, most of us always correct them in a
constructive manner.
Anyway, even if specs fail, there's still Sgwiki for him to
double check the suffix in case he didn't spot the correct bus.
Apparently, he didn't even bother to go check leh.
In fact, if he bothers to take a look at sgwiki and even after I
supported him with the link, he wouldnt be guessing whether it is
3001/7705/7706/7707 AND 9266/9276/9278 etc. The answers are already
there.
