The last time I bought gasoline was in 1997 or 1998 - I was on a bicycle trip and used my tent for the nights. I bought half a litre and used it for my camping cooker ;-)

But imagine the face of the station owner when I rode up to the air station and filled my tires, then cycled up to one of the pumps and poured gasoline in my pannier (it must have looked like that - I was holding the fuel bottle behind the pannier ;-)), then went to pay.
