Tide Times UK
I used to use TideTimes UK website, they started using ads and they got more irritating. I put in an ad blocker and the site started ordering me to switch it off as the website loses revenue when I block.
Oh well, sod you then!! I never go to that website now, I simply use the tide times on the BBC, an ad free service that I've already paid for. Sorry TideTimes UK but if you're going to irritate people then when they try to help themselves you "insult them", you can get stuffed and lose out completely.
