Quite true...especially on recent Sundays 
980 controlled by 2 depots: AMK and Woodlands.
Comparing between AMK and Woodlands, I feel that AMK treats service
980 with more respect by deploying newer buses like Merz Volgren
and also Merz Habits to cater for the higher demand on
Sundays/Public Holidays. Whereas Woodlands nowdays only dump those
massive CAC Nissans on service 980 7 days a week regardless of how
the demand is. The MB0405s and Habits from Woodlands come out on
service 980 only once in a blue moon.
Also to add on, Woodlands depot is showing favourtism to services
857 and 969 by giving them more bendies during weekends. I remember
service 980 durinng the Tibs days used to have lots of bendy buses
from Woodlands too, but not at all now. In fact, the Woodlands
deployment on 980 have deproved over the years especially with the
redeployment of the CAC Nissans on 980.
In fact, I still don't understand why the SMRT is doing this to
service 178 and 980. Till then I am still looking forward to see
the return of TIB658K, TIB665P and TIB673R on 980...
