I visited two Mercadona grocery stores in Torrevieja. Nothing wrong with their products or prices but the staff is often unfriendly and rude against people who doesn´t speak Spanish. That is in line with the general anti tourism wave in Spain. But in a place like Torrevieja, where a great number of the Mercadona stores costumers – perhaps the majority – are people from abroad, it doesn´t seems to be a wise business idea.
