Why are people always described as 'panic buying' when all they are doing is making sure they have a sufficient supply of a product ahead of a shortage.
If that is 'panic buying' then, for example, buying fruit and veg cheaply when in glut in order to bottle, jam or freeze them for use later when they are more expensive is also panic buying.
Having said that, I do think that there was panic buying this time because while the tanker drivers had voted for a strike the earliest date publicised for a possible strike had been 'over Easter', which was, when the panic started, over 10 days away.
Mr Maude could, of course have been being deliberately devious in what he did. By causing the panic this week he has put the tanker drivers and their union on the back foot by making people experience in advance what it will be like if there is a strike - and its working, the unions have already withdrawn their threat to strike over Easter.
