We drove to McDonalds for a milk shake. We specifically asked for a large Vanilla. When we got home it turned out to be something else altogether. Probably supposed to be chocolate but it was pale coloured, vaguely chocolatey but really not very nice at all.
We had to drive all the way back to get it replaced. The Canley branch does seem to be one of the worst McD's in Britain. It's not the first time we've had problems there.
