The other day at Multichoice I overheard a conversation
Person 1: Hi, what were you coming to do here?
Person 2: The channels on my decoder disappeared so I was coming to sort it out (machannel anathawa)
i.e. he had not paid and was going to settle his bill!
Another one I heard while on a ATM queue
Person 1: Hey you, you are taking long at the ATM. Are you fixing it or what?
Person 2: The ATM is giving problems
i.e. The account is depleted and there is no cash to dispense!
