[Margaret Pilkington]

It might not be to your taste Guinness but it will be acceptable to many others.....myself, I see it perhaps as one step up from Mc Donald's......maybe you don't.
Maybe those families who cannot afford to go to a restaurant, will go there.....and if the finances look up then maybe they will move to the next rung of tha ladder.

Many families take their children to these establishments in order to 'test the water'.....to see how their children fare in a dining out experience....because they know that there is more leeway given to children in a pub than in a restaurant.
A bit like breaking children into theatre by taking them to a panto first....giving them a taste of what is expected of them.
But, in any case you won't need to bother about any of that because you won't be a patron.
