You also see lost more people getting on and off rickshaws during the monsoon season.
That's the period from June to September when Kolkata gets heavy rainfall.
Sometimes it rains for 48 hours without a break.
In the older parts of the city, the road flood.
The water can rise as high as people's waists in the worst part.
When it's this bad, anything with an engine is useless.
But the rickshaw drivers never stop working, even with water all around them.
