If someone tells me that three restaurants did not help clean the beach, I can take on board that information as everyone else can too, we are all grown up so we can make up our own minds where we want to eat.
However, for the record. I hate sitting on beaches too, but I like to sit at a restaurant on the prom and look at the beach and see it's lovely and clean and I also want new tourists to the area to see the same beautiful rubbish free view.
