The "Double Hail" :

 

Two people, travelling together, trying to flag down a taxi at the same time.

Just wondering...

 

Do they believe that two arms will beckon a cab twice as fast?

 

Or maybe they think that a taxi wouldn't bother to stop if only one arm is extended, drivers never having seen this rare phenomenon before, of course.

 

Perhaps though, in a Pavlov's Dog kind of way, human arms are conditioned to respond when a yellow vehicle is spotted, an upper limb unable to resist the urge to thrust itself out.

 

Better than salivating I suppose...
