Running a profitable coffee shop is an exercise in speed and efficiency. You need speed to keep your customer line moving, efficiency to manage inventory, and a little of both to handle hiccups like equipment repairs.
The faster you can do these things (and do them well), the more product you’ll sell in less time—and without overstaffing. With any luck, you’ll have time leftover for things like planning your next location and keeping up with specialty coffee trends. Maybe even traveling to origin!
