The cabin he was in didn't have any seats, it's standing room only.
Such standing room only cabins are introduced to carry more passengers especially during peaj hours as they save more space which effectively means that more people can squeeze into the cabin.
The cabin was relatively empty and so he sat down on the floor with his head touching the handrail.
As the train moved and jerked, he knocked his head against the handrail.
He bursted out cursing and swearing at the handrail.
Everyone on board turned and looked at him.
He seemed to enjoy the attention he was getting and started swearing at the system and the management of the MRT.
Suddenly he was talking on his mobile phone to someone and again, he was cursing and swearing about the system and its management.
By now, everyone either knew he was trying to get attention or just couldn't be bothered with him and were ignoring him.
When he finally reached his destination, he went off while still talking loudly on his phone.
Two elderly man standing next to where he sat looked at each other and shook their heads.
Some wondered if he was actually speaking to himself on his phone.
