I find this hard to reconcile.

If we are to believe the Public sector workers, they are struggling to 'put food on the table' yet they can afford to travel North to buy what is in my opinion non essential foods and in truth LUXURY items of booze, toys, clothes.

Secondly, if people are struggling and living from day to day, how do they amass such lump sums as to bulk buy.

pay the public sector workers northern wages if they like Northern prices so much.
