Thefts from businesses happen all the time. This one is no worse than any other. Doesn't make it good of course, but we have insurance to cover such things and I suspect chances of recovery are high. The machine and grinders will probably be advertised somewhere and many of us forum readers will be aware of this and flag suspicious listings. Even if culprit kept machine and one grinder, they still have two more to off load. It would be a rare person that kept three commercial grinders for home use. I reckon putting GPS tracking devices into espresso machines for tracking theft is overkill. How common is such a theft, compared to, say, theft of till takings, fraud, or non payment of valid invoices? The article suggests one or two machines a year are stolen throughout Australia based on the reported thefts they mention.
