I actually saw "Expresso" on one of the over-the-isle signs at Walmart. I actually told the manager about that one. I don't think they ever fixed it (I'll have to check again on Friday when we get groceries).
In addition to mangled idioms, un-mangled but miss-used ones also annoy me.
My boss often uses "I'll be persona non grata" to mean he'll be out of the office (ironically its when he is IN the office he's persona non grata to the extreme). Also used to have a sales rep that used the phrase "I was out of pocket" to mean out of the office or out of communication ... I used to always reply "you were paying your own way?" He never understood what I was getting at.
ETA: Oh and people that over-use adverbs like "actually" ... and people that don't properly use ellipses ... can't STAND those people![]()
