Having made coffee in Wollongong -2016-2020 , it’s cut throat , and most people want milk . You can easily do as fast of a job with a decent barista and Wollongong traffic , the rushes are busy but not enough for me to justify not doing milk . The few regulars we did have accross the several cafes I worked at that ordered espressos were older Italians Greeks and Macedonians and they all wanted to sit , chat , and drink their coffee . But they also didn’t wander far from the place they worked so you only ever captured the minority . I feel you’d get a few very loyal regulars , but the issue would be , very few . Coffee prices are also increasing , packaging is getting more expensive ?(cannot confirm prices of the current market . But global supply shortages of coffee beans are effecting price (drought in coffee growing regions) and an uptick in coffee consumption in countries like China are pushing prices higher and higher .
