Just had an odd experience at Boots & Superdrug

Just like others have reported, twisting the newer pens no longer does the trick. Unfortunately, I got caught out without insulin needle as not tried this method before. I went into Superdrug today & asked for an insulin needle, made it clear that it's just a needle with syringe I need. They said they dont sell any needles 😐 At Boots, they wanted me to show them an example of what I wanted, which I did I did come clean with them what I wanted to use it for, as they were asking me all sorts of questions. Anyway, they said they don't have any. How can the 2 biggest pharmacy chains in the country not sell insulin needles? Surely they were not being truthful. Anyway, I will have to order them online and miss this week's dose.
