Citroen garage. When I ring up and try to book my car in, you say "No need to book, just turn up, we are open from 8".
So when I turn up at 8:15, wait outside for 30min, try phoning 3 times, all without any success, it is really fucking annoying.
Oh, and if you pay someone to make a website for you, with a handy location map, it would be a really good idea of the location map actually showed your location, not somewhere 2 miles away.
