Everywhere else is fine - up to a point; obviously there's the errors in bagging area and all that shit. But with M&S it takes me ages just to get the bastard thing to scan a code at all. There's only six actual tills in ours now so didn't have much choice but to do self service and honestly it took forever, stood like a twat waving my bloody manchego at the stupid fucking red light. What am I doing wrong?
