It drives me mad when shopworkers or whoever add 'at all' to the end of every question. "Do you want cashback at all?" No I don't want cashback at all. I also don't want a bag at all. And I don't have anything smaller than a tenner at all. And I don't have a Nectar card at all. The only thing I want at all is for you to stop adding pointless phrases to your sentences. At all. Phew. Friday.
