Off Topic, but still related to Svc 151 (SBS2696E).
Was on Service 90 (SBS400E) this morning at about 11.45am.
When Svc 90 reached tail end of MacPherson Road, it caught up with
SBS2696E on Svc 151.
Along Airport Road both buses went, with 2696E in front and 400E
behind.
When 2696E reached the left in left out junction with Tai Seng Ave,
the bus captain either got blur, or mistaken it for the left
turning slip and turned into Tai Seng Ave.
The bus captain of 400E horned the BC of 2696E, and passed the
junction. Saw 2696E make a right turn out back into Airport Road to
proceed back on the correct route.
