| Re: Couple
As Les says, rubbish. A couple always means two.
When folk talk about going for ‘a couple of pints’ they mean two, but then get carried away and stay for more. Informal usage means they know in advance they are likely to stay for more, but they say a couple. same for your ‘couple of hours’ example.
