Depends if it's BUSY or not or if I'm CARRYING anything heavy.
A) If the bus is BUSY I'll grab any seat, couldn't care less where it is UNLESS it's one of those SHIT seats at the back of the bus that face backwards.
B) If the bus isn't busy I'll go upstairs and sit on the seat directly next to the steps so I don't have far to go because I'm a LAZY BASTARD.
C) With regards to B)...if I'm upstairs and the seat next to the steps becomes free I *will* move there unless I'm 3 or less rows away in which case it would be STUPID.
D) With regards to B) and C) I never sit in the front row upstairs.
E) If my journey is SHORT I will usually stay downstairs unless A) the only seats free are one of those SHIT seats.
F) If the bottom deck is full and the corridor is blocked I won't bother wasting time checking upstairs, I'm happy to stand.
G) All the above is IRRELEVANT if they put on a SINGLE DECKER bus on one of the busiest routes in town. BASTARDS.
