Rules are rules, it's dead but humans are alive. We are
flexible. Actually if you tell us the problem about services 8 and
90, we can't do much also as many of us seldom take service 90 and
thus don't really know the situation. What I suggest is that you
can contact SBST or PTC and leave them to deal with it.
Also, SBST may have their reasons for doing so, before that getting
special concession from PTC.
