Last week i my best ever experience - In brief
Customer asks for giro - not regular postie
I refuse - no mate its in the other bag you'll get to you at 11am.
Customer - "i've not eating for 2 days, i'm starving"
me - "thats because you've you spent it on booze mate you ******* alchoholic - Just kidding i never said this but i wanted too"
Customer - "Please please jumps up and down on the spot a few times"
me - "sorry mate no can do"
Customer - "You ******** evil b******, hope you die"
