For me it can depend. If it's a decker - front seats upstairs. If they're taken, at the back upstairs, don't like the idea of sitting downstairs with the OAPs.
On a single decker, I tend to hit the front seats at the very front, not the 'reserved' ones for the OAPs. If they're taken, the back. Although in the past I have had a few looks from OAPs for sitting in those ones at the front. It's amazing how unnerving they can make you feel.
What about anyone else?
