SIR – On Saturday, May 26, I was asked if I would no longer take my insulin in the shop, which I have been doing for a few weeks (Greggs at Five Lane Ends), as someone has complained about it. The staff at Greggs were polite about this matter.

To the people who did the complaining; insulin-taking to a diabetic is a need, just like eating is to you; we need the insulin to live.
