Well, I have had a few funny glances when people take a look at my key ring with flashlight, firestarter, SAK, Leatherman Squirt, whistle, vial of water purify tabs, etc...

It's funny though, because the worst thing anyone ever says is something like: "What are you, some kind of Boy Scout or something?" If that's the worst people say, I think I'm doing ok. (Of course, at 40something, I probably don't look like a scout anymore, but, I am a leader in our local troop.)

It has worked the other way though. Once people start to know that you are "equipped", they start to assume you'll have anything. At sporting events with kids, if someone needs an ice pack, FAK, whatever, they start looking for my car. It's not such a bad reputation to have. I wouldn't change my behavior due to social pressure. Those will be the same folks begging for your assistance when something does go wrong.
