While you&#x27;re not exactly wrong (especially in the case presented), there are a variety of exceptions, for a loose definition of &#x27;work&#x27; - which some future readers&#x2F;searchers here might find useful.

Selling, being a service engineering, training, and some other things are also allowed with very careful restrictions.
