We were in Costa Blanca last week and in Carrefour's car park on the N332 at Punta Prima, there was an ice cream van.
It was a trailer/caravan type van, attached to a car, and had electric hook up to run the machinery, obviously supplied by Carrefour.
The couple looked "English," but as I didn't get an ice cream (too fat already!), I can't be sure.
But they were certainly trading...............
