Customers have called for easier and quicker shopping trips at the Northwick Road and London Road stores. A team visited the store to update trolley fixtures.
This included removing the need to insert a £1 coin or token to release a trolley from its bay.
Mark Easton, the general manager of Morrisons Canvey, said: “Customers in this area have told us that they want a quicker shop. The removal of trolley locks is just one of the many improvements we are making to our store.”
