I think its learn the hard way also best to look back on & laugh about it
Not that i've done many fluff ups at work - mainly through life in general quite regular i must like learning the hard way LOL
My 1st job after i left school I lost over £1000 that disappeared through the accounts that i was in charge of [despite my maths being the weakest link to which i only passed it this year lol] lets say i got my 1st verbal severe warning & had to re-trace all the accounts for a month both manual & computerised - lucky i managed to get it back & re print the invoices again. Funny i never wanted to do book keeping again lol
