Happened to be the other day, albeit late at night in a bar.

Asked for a "whiskey and soda". The concoction served tasted suspiciously like Rum and Soda. Take it back to the bar. Suggest that she might've poured the wrong spirit. The wait person argues that it was infact Whiskey and not rum. Ask her to check if she poured the right bottle. Pulls a bottle out to show that she indeed poured whiskey and not rum. Except, the bottle she pulled out was "Bundaberg Rum".

Comes back to me, says, "If you aren't happy, I'll make you another one"; without actually accepting that she might've poured the wrong spirit.

(Geez, how about accepting that you infact screwed up the order. Not it wasn't the end of the world. Accept the mistake, none the less!)
