Solution Required For Shopping Trolleys Clogging Mount Druitt Bus Interchange

Whilst using Mount Druitt Bus Interchange in its congested situation, the walkway at the bus stops seem to be clogged up with trolleys. This is because shoppers after shopping are placing their bags in shopping trolleys and exiting through Dawson Mall, Dumping empty trolleys in bus stops at the bus interchange. Something has to be done about this.

In the peak hour this is a nuisance and  is disruptive to all commuters. 

A suggestion would be to have trolley stations, along North Parade Mount Druitt, left  for picking up or  have them set up in between Mount Druitt Bus Interchange and the Back Dock of Best and Less, Westfield Mount Druitt. Plenty of signage must be displayed along  and towards the Mount Druitt Bus Interchange side. What would your suggestions be for this improvement?
