As you traverse the back lane (lorong) between Wharf Road and Central Road, you will find the last 2 remaining rusty metal flaps over sealed rectangular holes at the back of the Central Road shops from the late 1950s. What were the function of these metal flaps ? Were they pet doors or soy milk bottle delivery holes? The holes were small enough to deter burglars but then no burglar would want to go through these holes.
In the 1930s-mid 1970s, Sarikei shop houses did not have flush toilets, individual septic disposal or sewage treatment facilities. The bucket toilet was the de facto mode of passing motion. The bucket toilet was next to the bathroom and had one side facing the back lane for the night soil man to open the metallic flap for collection of the human excrement.
