watch for orange slips

i ran into starbucks on fifth avenue and 33rd street with a diarrhea emergency i could not hold a minute longer. i left my cab running, but right up against the curb, with hazard lights on, right in front of the coffee shop, at a bus lane that does not get used all that much, for UNDER 5 minutes, and i ran out to find a $115 parking ticket on my windshield. i would have made around $180 that 12 hour shift. subtract the difference and you have my income for the day. are we cabbies not human enough to take a shit when we badly need to?
