 Person2:  What do you mean ?

 Person2:  Crikey . Where did this happen ?  
 Person1:      In Taichung , I think .  
 Person2:  Oh , right , I hear they have a lot of this kind of problem down there .  
 Person1:      Really ? Well , anyway , they pointed their guns at him and said , you know , keep calm and drive out . ... we don't want to hurt you ... we just want your car .  
 Person2:  So what happened ?  
 Person1:      Well , he drove out , and when he got to the booth to pay the attendant , he pretended to have an epileptic fit , you know , to scare the thieves away . The attendant was no help at all , even though the guys were holding guns in plain view , he did nothing .  
 Person2:  That's terrible .  
 Person1:      Yes , makes you think , doesn't it ?  
 Person2:  So what happened next ?  
 Person1:      Well , he kept on pretending to have a fit , so they freaked out and just ran away .  
 Person2:  Well , he sure was lucky .  
 Person1:      I'll say .
