I'd ordered the pancakes, they come with sausage or bacon, I asked for sausage then asked if I could also get a side order of two eggs...
Me: Can I get a side of two eggs with that?
Waitress: You want them instead of the sausage?
Me: No, I want a side order with the other stuff.
Waitress: (looks confused) Well, that would be A la carte and I don't know what it would be in place of...
Me: Um, never mind... just leave it the way it is.
WTF, I do not think that word means what you think it means. I just didn't have the energy to try and explain it any further, hadn't had coffee yet.
