My son sells, among other office products, a large flatpack cardboard waste-bin, c/w poly bag liner, used mainly for office wastepaper, cola cans, paper cups, etc..
He gets regular calls from customers asking him to come & empty the bin as it's now full! How he stays polite to the dolts who whine " Well, your number is printed on the side of the bin." is beyond me.
I keep telling him to advise them they need to compact the contents by getting in the bin and jumping up and down, but he's too sensible, like his Mum!
