People who just abandon their empty supermarket shopping trolley in the middle of the car park instead of returning it to the trolley park. Lazy barstewards!
Parents who let there toddlers run riot in shops / supermarkets etc, or let them lay on the floor having a screaming fit.
Managers at work who state the bleeding obvious and pass it off as some brilliant piece of inspired thinking.
Such classics as:-
"Do it right first time." - Thanks for that. There was I labouring under misapprehension of having dozens of attempts to get it right.
"Reducing costs will have a positive affect on our EBIT." - No s**t Sherlock.
In the same vein. Management concepts that take a well established and obvious process (such as fault finding / rectification) that is largely common sense and try to make it look like something inspired and novel by inventing a new name for it. Such as "six sigma", "visual planning" etc.
Management buzzwords - "helicopter view", "going forward", "leverage", "paradigm", "synergy / synergies" etc. I saw an absolute classic in a PowerPoint presentation from our sales team - "deep dive homunculus". I think they do it to give the impression that they are more intelligent that they actually are. Hate it!
