Sometimes I feel like I'm not cool enough to come here, but I still do. I;d come here more often, but they close at 7pm and aren't open on Sundays.
They use an iPad for credit cards. On one hand, it's neat since they'll email you a receipt, but it's also kind of gimicky. Who really needs a receipt for a cup of coffee?
Another thing to keep in mind is that the app will ask how much you want to tip, so don't be surprised. I typically don't tip for a cup of coffee, but I was caught off guard the first time and felt compelled to tip. It's a big screen facing everyone in line, so you feel kind of under the microscope.
All in all, I'm glad a place like this exists in Auburn.
