At least one staff member must speak Spanish.
Yes, maybe you think is unbelieveble but most of resorts bars or even restaurants in spanish coast don't have anyone who speak spanish.. how many english are living in there or how big are the english colonies in the coast??
It has been brought to our attention that in the Cabildo’s Tourism & Planning Department law regulating bars and restaurants, published as decree 90/2010 on July 22 2010, certain minimum conditions are stipulated, and failure to comply could lead to inspectors charging you an on-the-spot fine of up to €3,000.
The decree states quite clearly that you must have staff who speak Spanish. We presume that employing one Spanish speaking member of staff would fulfil this requirement.
