Sim Lim Square has been in the public eye for a long time for all the wrong reasons.
Recently, it was in the news after one shop owner returned a refund of more than $1,000 in coins.
Its management has also appealed to the authorities to "take a tough stand against the recalcitrant retailers".
Over the years, the electronics hub has gotten flak for shop owners' dubious antics. Here are some reasons for its rise in notoriety.
This is possibly what Sim Lim is most infamous for. From video cameras to iPhones, various shop owners at the mall have been known for ripping off customers, especially tourists.
In 2012, a complaint booth was set up at the mall to tackle the problem, but it did little to help. Name-and-shame lists that were put up were torn.
Some shops took to making their names less conspicuous on signboards, or even changing their names to avoid detection.
Overcharging incidents are usually shared on Facebook, forums, blogs and review sites. In one such typical case, a reviewer on TripAdvisor said that a shop sold his brother a mobile phone for almost $750, up from the $270 first agreed upon.
The extra amount was apparently the cost of warranty.
2. Threats and intimidation
Over the years, Sim Lim shop owners have drawn attention for being threatening or violent towards customers who did not want to buy their products, or wanted to change items.
A video on YouTube (some strong language) showing a salesman spewing vulgarities after he was asked for a breakdown of the cost of a video camera was uploaded in 2011. It got more than 200,000 views.
But such incidents are not uncommon at the mall. In 1989, a salesman threatened to beat a Taiwanese tourist who tried to change an item he was overcharged for. The tourist had bought a Toshiba walkman for $380, more than double its market price.
