I have become "memorably" numb?

Tonight I had my first "you might be fat if..." experience.

You might be fat if...

...The lady who used to work at the donut shop sees you 2 years later at her new job where she's a hostess and she recognizes you but you don't have any idea who she is.

That was my big clue this evening.

Backstory: I go to this one donut place mayyyyybeeeee 4 or 5 times a year. (Not saying I only /eat/ there 4 or 5 times a year but usually Mr. Buffie just runs in and grabs a half-dozen on the way to work while she-who-is-not-a-morning-person waits in the car. So I personally don't step foot in the donut shop all that much.) /end Backstory

Tonight we went to grab a bite after an obscenely long day at the office and the very nice hostess lady says "Hi! Haven't seen you in a while!"

I'm thinking "Hi, haven't seen you... uhm, ever."

Then she says she knows me from the donut shop, where she used to work 2 years ago.

What does that mean???? Who has a memory like that? Does that mean I'm memorably fat? I've always jokingly wondered if they have fat "Wanted" posters in places like Chinese buffets and donut shops (like John Pinette says) but now I'm thinking - do they /really/ keep tabs???

Mr. Buffie is the one who pops in there 90% of the time and she doesn't seem to recognize him at all.

Not exactly paranoid but definitely perplexed and possibly even intrigued....

What makes someone memorable? (I know what makes someone memorable to me but what's the general consensus? I feel bad for not remembering her. She was a nice chick.)

Are you "memorably" fat? What was your first clue?
