Things not to say to retail employees during the holidays

"It's a shame your store is closing.  It's been all over the news."

Someone said this to me while we were woefully understaffed and had a line that was unconscionably long.  She smiled like a predator, and I did not throw anything at her or burst into tears.

I did not say, "We are aware that we will be the last to know.  This is why we are searching for other jobs.  This is why our turnover rate is ruinous.  This is why we are stressed (one of the reasons anyway), why our smiles are so tight and fake-looking, and we don't need any maliciously cheerful reminders that our jobs hang by a slowly fraying thread, you big jerk of a harassing bully.  Happy holidays, ma'am."

This is a public service message just in case you are tempted to say anything that assinine this coming year if the economy is still unwell.  But I know that no one who reads this blog would ever be that rude.  :)  Thank you for that.

If you've ever worked sales or retail, what ridiculous things have you had to put up with customers saying (and/or what's the best line you never said)?
