I've always found the 1-2 seating configuration towards the front of Arriva Pulsars 1513-1523 to be rather unusual. I think the HW07 Citaros that GNE used to have had a similar seating configuration.
Same with the side facing seats over the rear wheel arches that Arriva's ex-London DAF ALX400s had (as well as the Y-reg Lowlanders to a lesser extent).
