The junction at Chai Chee Road and Upper Changi Road was flooded again after heavy rain on Wednesday afternoon.
But Mr Ivan Lee, 48, a sales assistant at a cake shop at Chai Chee Road, said Wednesday's flood was not so bad compared to Monday's.
He said he had been working in the area for more than a year, and Monday's flood was the worst he had ever seen.
Video footage of the flood that day showed the water to be knee-deep.
The flooding happened around 2pm and lasted two hours, said Mr Lee.
It was so bad that motorists were stuck at the junction for over an hour, he added.
"At one point, I saw both the driver and the passenger of a taxi get out to push the taxi to higher ground together," he said.
"The passenger was wearing business attire and got completely drenched. He looked like he was going for a meeting."
Mr Lee also told The New Paper that he saw PUB representatives installing metal grates on the roadside gutters a few months ago.
"But that didn't seem to do much, with all the flooding recently," he said.
Others working in the area were not surprised by the flash floods.
Mr Yap Wei Choon, 40, a stallholder at Food Hub @ Chai Chee, which is next to the junction, said the area floods every now and then.
"But these few weeks the floods are quite bad," he said.
He has been working there for just over six months.
