Late one night police cars crowded the parking lot, but no one was at the pumps. Was it closed? Had it been robbed? As it happens, it was neither. Still, a Fort Lauderdale officer sternly warned that this is among the most dangerous places in town. Oooh, we're shaking! It's the entertaining kind of danger. For example, when a frantic customer didn't know the English word for his desired purchase, he made a crude pantomime instead. The clerk never missed a beat, handing his enthusiastic patron a condom. A youthful employee may wink and throw in a free bottle opener with your Friday-afternoon beer purchase, though such gifts may be just as easily snatched back by the disapproving boss (his father). You just never know at this family-owned Amoco. Pump your petrol and take your chances.
