I had heard that Boots give problems to us, so I decided on the following tactic:

I went in on a busy Saturday morningand was asked by the girl behind the counter why i needed them. I replied, why do you think I need them.

After getting her reply of 'we can't sell them to you if you are on a diet' I replied that I needed them to check my urine on a daily basis and that i was not in the habit of peeing in a bottle for fun and I was not into urinology.

I got them but as a parting gesture I asked her 'if I came in for condoms, would she have asked me what I wanted them for'?
