Choking the toilet
There was this solitary toilet next to a big restaurant. You can imagine what it was like when the customers are all full, belly like 48 gallon drums. All will head to the toilet at the same time. Sure jam. Big queue, long queue. The the jamban jaga got smart. In order to reduce the number of people queuing up, he raised the entry fee to the jamban. He solved the long queue problem. But there were no jamban around. Not his problem. These overfed people must find another jamban or go to the backlanes.
