Just had a beauty in my office.
My colleague arguing with a guy in the states about commissioning something, My colleague says 'that step wasn't in the procedure you sent me, you'll have to change that' Other guy says 'well it came out the manual', 'well the manual must be wrong then' Other guys parting shot to my colleague 'Emmmm, you wrote the manual'
My on the floor with sore sides which has happened more than once today.
