SPITTING IS UNACCEPTABLE.
Bus operators are now equipped with DNA kits to assist with the apprehension of offenders.
How is it possible that I resisted the urge to spit? Do you think the driver slams on the breaks? Then, marches down the aisle swabbing the buccal mucosa of each potential spitting passenger?
Spitting is gross - but could this be over-reacting? How often is spitting an issue? Will the fines pay for the cost of buying the equipment for each bus?
Oh, and on an unrelated topic - yet still a sign. This time in the hospital.
Abusive behavio(u)r will not be tolerated - including "excessive intoxication".
Good to know that "just right intoxication" will not be a problem.
