Be on duty and deliver
A barber and a barista have one thing in common: they both make and deliver.
Somewhere between the making and the delivery, there is a risk of errors. What if the service messes up your order? Or your hairline?
But don't let those "risks of errors" be excuses to not deliver.
When you go to a barber, you know that your hair will get done. When you order a Starbucks coffee, you will receive the order on the spot. Every time.
No matter what goes on behind the scenes, people want to see someone on duty. The expectations can be different, but being on duty keeps the connection and builds trust.
When you decide "that" is your work, be on duty and deliver.
