I've been here before and one of the machines was not working. The next time I can was at 8:30 pm and the store had a sign that said be back in 3 minutes. I thought that it was reasonable to wait. I walked around and came back 10 minutes later. Still no one. I decided to run another errand thinking maybe it was possible that someone would return. I walked to the boba shop across and one of the workers reported that the sign was up there by 6:30pm that night and no one returned since. Very disappointed. As I decided to get boba, I saw multiple people make the attempt, wait around and then come back. Not sure if this was an off night or this is a typical business behavior
