Garden City - Christmas Last Minute Night Shopping

Last Night, major shopping centers in Brisbane opened until mid-night. I thought there were a lot of people. But I went to Garden City around 7pm last night. The car park is not full. The shopping center is not busy. I went to there on Thursday too! There were more people on that times. I think that is because there was heavy rains around evening time last night. Moreover, the most of  people have done their Christmas shopping.
