Ah yes forgot to mention. A REAL espresso machine vendor will show you how to use your new machine before you walk out of his establishment...not on a demo, on your own machine...that is ofcourse unless a machine is purchased by mail order. Almost every single machine we sell goes out the door in this way. Everyone gets a lesson on the machine they are buying, they get some freshly roasted coffee ground the right way for the machine so they can go home and enjoy it straight away, and if they have also bought a grinder, it is set up in front of them together with the machine they are buying. Otherwise, you may as well all go & buy your machines in the box from the a department store (and never know how to use them properly) and eventually lose the expertise that exists in companies like mine to help you with ongoing after sales service with the machine you bought from us, many years down the line. This kind of service takes time, and time is money so it is a relatively costly way to conduct business however if you wish to invest in your business by way of your clients, that's what you have to do. Just having a dig at short sighted traders who look upon their clients as "oncers", instead of a valable resource to cultivate long term for all their future coffee needs. Have you asked those who sold you the machine why you are not getting a crema? If not you should...they should be your first port of call for help, and they should be able to help if they know their business properly. Goodluck, FC.
