You know the clothes you wear really do make a difference. When I'm in full biker gear, people are a little more cautious to approach. When I'm dressed up or have on nicer clothes, they're not as apprehensive. Like agentfortyseven, I do tend to look like I have a scowl on my face so that probably doesn't help the situation any either.
A friend at work told me once that if she didn't know me and came across me dressed in full biker gear she'd be terrified! Hahaha! Another time I walked into another friend's high end hair salon, again in full biker gear with sunglasses on, and just stood there by the door waiting for my friend so I could take her to lunch. I found out later on that I scared the hell out of the receptionist. She didn't know who I was or what I was gonna do 'cause I was just standing there. I guess my posture seemed threatening. Go figure!
