Had a beer in a well known restaurant - bar ,asked if the wi fi was not working as I had no signal , the answer no problem we now change once or twice a day .Too many people sitting outside the bar and using the free wi fi . free for customers only . I had a conversation with one of the owners ,he said he had heard that people where trying to hack his wi fi and said if he finds out he will report it to the correct people as he thought it was theft , Mike .
