A couple of times at things like work events that have been standing up nibbling and drinking type things I’ve just said to someone could you stand there a minute and not move, to create a barrier to do my jab without worrying about being knocked etc. no one ever minds doing that for me.No one has ever given me jip although there are times when I have to be careful such as injecting near boisterous kids who may knock my pen, or when wearing a dress, I couldn't inject discretely.
Sorry you experienced that incident. Most people don’t even notice us injecting (and yes I suspect a lot of us have gone through tights/shirts/… when we have no access to bare flesh).I got hassle in a restaurant once I got the novorapid out and a needle and put it on the table. Idiot on next table called me a bleeping junkie. So I just discretely did my bolus through my shirt (not going to argue its a no no) and put the kit away. Idiot complained to a waiter he got the manager and idiot asked to leave. Manager has a type 1 chef so understood. Once on a train I did a bolus and explained it is a hormone not drugs he was OK after.
