Expect many JB retail shops and eateries to fail in 2-3 months' after SG has matched JB tolls, which is likely to be in 1-2 weeks' time.
SG is waiting for a little while because they are expecting that MY may change the toll charges anytime soon due to political pressure, as quickly as they implement it.
If 3 weeks still no change, than they implement accordingly. Actually SG is more than happy to increase the toll, higher the toll, more revenue collected and best of all, easy money. Singaporean can choose not to go to JB but SPR must go home to JB.
