Painfully conscious when sober Earl ;
always enjoy straight point .
However, talking drowsy :
how did Steve came to this ; I've been answering Bruce's . ?
And where have you been hibernating ; this went around on 7th September .
I know yo' folks are bit slow behind (the date line) ; but this is bit
extreme .
Moonwalking like this, you have the hide to "wake" me up on rechews ?
Disregarding the cosmetics I agree with you it is rather pathological
approach to process ;
we all have our ways , this one pays of with FDA , EC ; ISO ........... ;
inspections love to "see" something they can comprehend .
Don't give them simple things to tick and you spoil the game both ways .
Did you ever had a tie round your neck ? to call me a pretender ?
What is one of your "normal" MLB's ; bigfoot's footprints in ketchup ?
And please think of your future customers before you answer this one .
Cheers mate, good to hear you any way paul

normal MLB's.
