Recently had a dinner-party (went to lots of effort, lovely food, lots of wine, blah blah). Two couples came bearing a bottle each of that weeks Tesco half-price offer (plus in one case a bar of chocolate), then proceeded to drink the house dry, in one couples case til 3am. Please don't get me wrong, am def not the penny-pinching hostess, and most certainly will always keep the drink flowing, just thought it a little mean.Maybe the fact that there was a slight element of "duty" involved, ie returning hospitality to guests has coloured my view. If dh and i are invited anywhere, would always bring two bottles. Is one (cheap) bottle per couple the new black?
