Sagan is what, 23 years of age? Can we expect him to be a Saint? I never made it as far east as Slovakia but the further east you go in Europe the more liberal the phrase "acceptable in public" becomes.
Campy, Sagan doesn't wait for the worlds best cyclists - what makes you think he's gonna wait for all those vans on the otherside of the pump just to not have to pull the hose across the back of the car? He's obviously thinking about "pumping" some other fluids... If you wanna sit there and whistle Dixie in the back of beyond waiting for 15 minutes while those vans fill up with 700euros worth of petrol more power too ya. If he drives like he rides he'd be 25 miles down the road by the time your slow ass pulls out the gas station
