Low Tolerance Level

I was just walking behind an indian lady the other day in Raffles MRT station. As the platform was kind of crowded then, she has accidentally stepped onto the toe of a lady who was sitting on the waiting bench. A loud "OUCH" was what we hear next and everyone just turned and look into their direction. The indian lady apologized and walked away... Those sharp pair of eyes still follow... Huh... wonder why tolerance level of the lady is so low.... Can't help it but to roll my eyes
