Of course we feel barista training is very important however general staff training such as customer service and h&s training is also needed.
A barista training program could be three or four days of training, two days of training with a trainer and two days practical training where staff practice serving customers.
Making a cup of coffee in a training course is different then actually working behind a bar and this should be practiced.
Customer service training is also extremely important. Teach your staff how customers should be served. Do you like them to say Sir and Madam or is 'mate' good enough? Should they only serve one customer at a time? How about eye contact and body language? When should tables be cleared and how many baristas should work on the queue at a time? Do your baristas know how to handle a complaint? All these things are extremely important. Of course we can help if you need some help. Please do think about your training program. A great coffee shop really comes together when the staff are properly trained.
