Ooooh dear, we are becoming a little bit harsh here!
Can you remember everything you need to at work? If someone asked you a question, could you answer straight away without looking for the answer somewhere? Do you never make a mistake?
Whilst I do appreciate that some of these errors are real bloopers, some of them are little mistakes (like superfree chips, a wording error surely?) and really not that bad.
I have a full time job and a family and considered being a consultant but decided it would be too much for my head to handle at the moment. Some of these consultants are in similar position I am sure!
BTW, from what I understand, consultants need to go on quarterly training to refresh their memories and catch up on any new information and I would honestly say, if they are that bad, then you should mention it to them and then to head office.
Just remember though....... they are human!!!
