Are you serious?

My sister is small and cute. She is peppy and blonde and likes to play tennis, run, do workout videos, and cheerlead. This morning at work, a male customer was chatting with her and asked,
“So, when are you due?”
“Sorry, what was that?”
“When is your baby due?”
*blank stare*
Then he proceeded to reach over the counter and pat her belly(!).
“Oh, it must’ve just been the apron…”
Riiiight.

This sent my sister into a morning of emotional turmoil. When starting her lunch break, her boss asked her what drink she’d like. “Heh. I’ll just be having water today…”
Another co-worker suggested that next time something like that happens, she could reply, “Actually, I just recently miscarried.”
