You're HUGE!
Please don't say this to pregnant ladies. It isn't always what we want to hear. Yesterday the clerk at a local store told me that I must be due tomorrow because I was so big. Then she continued to inform me that she looked like me at 8 and 1/2 months. As I tried to pay for my granola bar*, she went on with, "are you sure you aren't having two?" As I tried not to cry, she let me know, based on what I am sure is advanced medical training, that my baby was too big.
So please, don't say "you're huge." Especially if you want repeat business from your customers.
*notice I wasn't buying a snickers or a pint of ice cream. I was buying an f-ing granola bar.
