Did you steam their milk nice and creamy at least?

You sexist and chauvinistic bastard, how could you do that to them? They can't live without forty cents.

@ #8 - And then the next person would expect the same and so forth. OP, you should have stated that it is posted on the menu and they are no different than any other customer, right before you spit in their overpriced designer drink and said "oops, my bad".

Anyone thinking of the

Just explain to them with condescending politeness that fancy math like that is too difficult for the ladies. You're going to be stiffed for the tip, so you might as well go out with a bang, not a whimper.

Grammar mistake: MY being a sexist...

What if they forgot their reading glasses?? Than you're a jerk to old people!

If you want to see real sexism and gender chauvinism at work in the barista service business check out what coffee shops near universities in New Zealand are doing. They charge male customers an extra $0.70 to $1 over the cost of the beverage simply for being male. Some female baristas are jokingly calling it the "dick tax." Not because the men act like it, but simply because they have one. Started as a protest to increase employed women's wages... Which is odd as they weren't charging male CEOs or overpaid Execs for it, they were charging male students who can barely afford anything. It caught on and now other coffee places in other countries do it, not as protest, but out of misandry and money-mongering. Somehow, I don't see people catching on to the idea of a "**** tax"... But for the OP's case... There should be one.

I always hated when the sex card was pulled just because you have to give an answer they dont like, men or women.... It's just desperate.
