A bloke starts a new job in a sex shop. His boss has to go on an errand, so leaves our man in charge of the shop floor for a while. A black woman comes in and starts browsing the dildoes. "May I be of assistance, madam?" enquires the bloke. "Yes - how much are your dildoes?" replies she. "They're all £35." "In that case I'll have a white one. I've never had a white one before." As she leaves with her purchase, in comes a white woman, who asks the same question and gets the same answer. "I'll buy a black one," she says, "I've never had a black one before." Then in comes a chav woman. "Oiw, ow much are yee dildoes?" "£35 for the white, £35 for the black." "Ah okay. Ow much is tha tartan one on the shelf?" "That's a very special dildo, madam. It's £165." "I'll ave it," says the chav, and she leaves with her purchase. The boss then returns and asks our man how he did. "Pretty damn well," is the reply, "I sold one white dildo, one black dildo, and I sold your Thermos for 165 quid."
