So I'm at work earlier and the phone rings...
Me: Roth Graphics.
Customer: Hi, is this Rebecca?
Me: Yes, it is.
Customer: This is XXXX XXXX. Hey... does anyone ever call you Becca?
Me: No. Well, my mother does, but just her.
Customer: (laughs) Oh-kayyyy... gotcha. So Rebecca....
Moral of the story? Don't call me Becca. Kthxby!
