Parking is nearly always free in Greece but in the UK it is usually paid.
When you are served coffee in Greece they normally bring you a glass of water with it. Although it is free you have to specifically ask for one in the UK.
In Greece when you order an alcoholic drink they will bring you snacks to go with them, not just just a few bits but I have had a whole plate of canapés turn up. But as a minimum with a beer you’ll get a bowl of potato chips/crisps.
