Not written a letter but have asked peeps in offices if they were giving away free stuff, for free, without being specific enough to actually know if they were either giving stuff away or if they were actually giving stuff away
Used to chance my luck in London quiet a bit and would always come away with somehing kr another
But asking some one specificly for something that they have thatypu need and not paging for it is a bit more lielybto end up with a no than a yes and then they'll know you want it and will bold onto it even tighter
