Big Magnets and No Business Cards

I went on a home visit yesterday and called in at Half Price Books (one of my favorite stores) on the way home.

When I came out of the store there was a woman wailing and shouting down the phone in the parking lot. I'd never seen anyone so hysterical. Anyway, I was walking to the car, when another woman approached me. I thought she was going to remark on the wailing Banshee, but instead she said "You're a masseuse?" (yes, I dislike that term as much as the next massage therapist).
She had noticed my car magnets and started a conversation where she wanted to know where I worked, how much I charged etc.
Meanwhile the wailing Banshee was getting even louder.
It was a sort of surreal few minutes. It was nearly like some sort of test whereby I was being tested on whether I could still talk about what I do when someone is having a total meltdown nearby.

Anyway, I didn't have business cards with me.

What's the first rule of thumb for every business owner/massage therapist? ALWAYS have business cards. You'd think I'd know that by now, right?
Anyway, the lady had a writing pad and wrote down my information.
It's funny, I always think that no one notices those magnets on the side of the car, but they do. They're an easy and cheap marketing tool and you never know who sees them!

As for cards - well, I REALLY should have been giving one to the Banshee too.
