Like the manager and the rest of the employees...wouldn't want to interfere...might not be prudent... 'YO, break out the popcorn and video peeps, let's see da tranny get killed'.
As for the employees; they should be held accountable in some meaningful fashion; but doubt they will.
(Remember the 'Security Guards' who watched a similar event at train station; where girl was unable to defend herself against a gang attack. (Despite her pleas; Security did nothing; and were not held accountable; even though they wore uniforms and badges; which at least implied, that they should.)
