Interesting how the take on "personal space" has cultural differences. On a virtually deserted beach in Portugal, we were nonplussed when a large family of locals arrived and plonked themselves down right next to us. Yes, we moved away down the beach, no doubt adding to the unfortunate reputation of "Brits Abroad". Had a similar experience in Sweden, where we were happily relaxing at a lakeside picnic table, and with other tables vacant, a Swedish couple decided to join us. Our initial discomfort quickly faded, and we had a pleasant chat.
In 'traditional' restaurants in Portugal everyone happily piles in to sit at long tables, no matter who is next to you. It's a chance to socialise.. I think your presence on the beach may have indicated the 'people' area to them, and they fell in with that. They are very social and wouldn't think of your space as 'personal'. We've had many an interesting conversations with other nationalities through this tendency when we lived in Portugal.
