Disappointed in Greek Hospitality

With the exception of my friends and relatives, who have been absolutely wonderful hosts, I'm a little disappointed in Greek hospitality. I hope that this is just a wrong first impression, or just the region we're in right now. I'm not finding people to be very friendly or open. It's hard to find a toilet to use except in large service stations or museums, when I ask to use one elsewhere I'm invariably told "no". Alix has better luck; perhaps because she speaks English to people, perhaps because she's a woman, or perhaps because she's just better looking!
