so , i was in barcelona a month or so ago and had an early flight to rome . i was catching a bus at 4am and this car comes out of nowhere and offered me and the other 3 people there a ride to the airport for 12 euro . it did n't even look like a cab . sketchy . yikes ! that would be really scary ! ! i hope you did n't get in the car ! we did . this british chick convinced me it was worth the risk . the chinese tourist couple just went along with it . i refused to put my backpack in the trunk and rode up front with it in case i needed to tuck and roll hah . had my phone out with the gps to make sure he was actually going to the airport . it all ended up being fine ... aside from the speeding . thank goodness it all worked out ! it sounds like you took a bunch of smart precautions !
A suspicious, unmarked car offering a ride to the airport raised apprehension and safety concerns.
