BTW, i suggest that your MIL look for shidduchim in gateshead in the fuutre, she will gain doubly, first of her children will live farther away, and second of all the kehilla doesn’t allow wasting money on shabbos shoes, – or even on souvenirs by chasunahs.
All jokes aside, i realsie that there is more a t stake here than shabbos shoes or paper plates, and wish you jmuch hatzlacha in dealing with you mil.
