Absolutely - I get endless amusement from injecting in public. Sadly I never get the attention I feel I'm entitled to! I hate insulin pens so I still use syringes, and for some reason no-one ever thinks I'm a junkie or anything.
On the whole, no-one cares. Most people aren't looking, they've got their own stuff to concentrate on. And if they are looking, so what? Why do we need to worry about the approval or otherwise of complete strangers in restaurants? I truly don't understand why anyone cares. It's not like you're doing anything shameful. There is no way I would ever inject in a restaurant toilet - it's bad enough having to pee in them! I've always injected at the table, and only one person has ever commented. I used to keep all my kit in a little tupperware box, and the waiter thought I'd brought my own lunch to the restaurant and helpfully informed me that you're not really supposed to do that! So I showed him my tasty insulin & syringes and asked him if he wanted to try, and he wandered off. He didn't get a tip either.
You've got to look after yourself, and it is much more hygienic to inject at the table. Other people's opinions (or your perception of them) are, at best, a minor distraction and must not be allowed to dictate how you look after your diabetes. If they don't like it, they don't have to look! :wink:
