i think there's a misconception betn a 'raid' and a 'routine check'.
raid /reɪd/ Show Spelled [reyd]
–noun
1. a sudden assault or attack, as upon something to be seized or suppressed: a police raid on a gambling ring.
many bros had very often mistaken a 'routine check' as a 'raid'. eg they see a police van in chinatown. immediately, they jumped into conclusion that the police were conducting 'raids' in that area. raids are what you often seen in HK dramas, which matas budged into gambling dens, whore houses, taking the culprits by surprise. they will usually push open the door, shout 'CID!!! All of u, hands behind heads, face the wall'' .. followed by rummaging thru the individual rooms.
whereas routine checks are usually 'Reviewiendly' visits to the joints, checking if the gals have valid working passes, if the shop setup meet the requirement, if the gals were carrying out their duties in a 'clean and proper manner'. (of cos if condoms are found in the premises, you chia lat liao!)
so far, dont hear a lot of major raids in Spore. maybe the routine raids in Geylang, or last time when police raided the 'uniform joint' near chinatown (which appeared in TNP). other than that, I think chionging here is still 'relatively safe' as long as you are not caught having sex in the premises.
