Store layout is not as big and fancy as the new larger Coles 'superstores', but the smaller version is great for your smaller shopping trips. A shame that you need coins to use the trolleys though. Most of the Coles staffers at the Dee Why store are pleasant. Like most things I suppose, they have some really good staffmembers that give brilliant customer service. And then there's the odd few that you consciously seek to avoid in future visits.
