Some of us have been there before, but all of us have derived a certain childish pleasure from people mistakenly pressing reply all to an email, or sending one to everybody asking the most banal of questions.
So spare a thought for the hapless Barclays employee who, we presume mistakenly, sent an email recently to the banks entire global address book and copied in Sir David Walker, the new chairman, asking about how to book a courier.
Having only just got his feet under his new desk at Barclays HQ and with a to-do list longer than most bank chairmen, Sir David could be forgiven for not knowing the banks courier booking process and frankly has little time to even contemplate it, should he ever want to.
Thankfully Sir Davids PA was gracious enough to respond to the employee and everyone else at Barclays throughout the world.
However, the response didnt shed any light on the matter: "Unfortunately, neither of us can help you."
