I guess that's true in touristy places but in general there's nothing stopping anybody from using the WC, just walk in. Would be nice to buy something but asking politely will do too, I've never been turned down. In Turkey they really like putting formal structure to that kind of stuff and venues at the high street sometimes have a lock with a password which is printed on the receipt with your purchase. One particular McDonald's was a pioneer in this, as their location was at the most crowded and central place where people used to meet before the proliferation of cellphones.
