Last night, as my co-workers and I left our office at about 22h15, we stumbled upon conclusive evidence as to the identity of the primary culprit of alleyway urination. Caught yellow red-handed was one Yellow Cab taxi driver relieving himself against a building wall in the alleyway. He was midstream, and appeared somewhat uncomfortable that he had no choice but to finish in our presence. But it makes perfect sense! Taxi drivers have got to go somewhere, and dark alleyways seem like an obvious receptacle &mdash I can't believe I had never previously suspected them! Two things this incident has taught me are: never ask for change from a taxi driver, and never pay with your credit card (unless you have plastic bag handy into which you can place the credit card for later boiling or combustion). Because, one thing's for certain: this taxi driver most certainly did not have a bucket of hot, soapy water sitting there in which he could thoroughly scrub his hands after his business with the wall!
