Einstein was full of crap

Einstein defined insanity as ‘doing the same thing over and over and expecting different outcomes each time’. In fact quite a lot of the time the outcomes are different.
The sort of outcomes I am especially interested in are the answers ‘yes’ and ‘no’. Quite often I am told ‘no’ by customer services. After some screaming and shouting, having the phone put down on me, swearing, speaking to several representatives, supervisors, managers for sometimes hours (I really enjoy it), quite often I am told ‘yes’.
