The phrase "at all" is getting completely out of hand in the UK.
Yep, totally agree - it reminds of the much older "if by chance" which is almost as nonsensical.
What is bizarre is that if you add "at all" to then end of your question, then there is a much better chance that the person will answer in the positive.

Wife: No dear, I haven't.
Me: What, none *at all*?
Wife: Ah, well as you have said "at all", then yes, i saw a pair in your sock drawer.
