Say, is there any place in the world where the shopping trolleys get the minimal regular maintenance that they need?
Everywhere I go, the trolleys all have wheels which have come loose and could be tightened with a wrench in seconds, but instead are left to rattle and wear into an early grave.
In the name of the FSM, is there any shop in the world not too dumb to maintain their own infrastructure? Anyone???
