No, because I decided not to get them online! People who work in chemists act like they are consultant doctors sometimes. A friend bought some Imodium before going abroad. the woman started asking him about what he wanted it for etc.
The other set of shop workers who get on my nerves are the ones in children's shoe shops. They act like they are consultant foot paediatricians. (if such a thing exists!)

But to return to your post, what possible reason Boots, or any of its minions can have for objecting to ketostix. It beggars belief.

I tried to get an electric comb to kill headlice from Boots once, and was told they didn't sell them because they were not very effective. I said 'but you are selling those chemicals which you and I know do not work at all!' The guy had the grace to blush.
