Rang in the morning to discuss a problem with my plaster cast. Was told to come in to a and e, got there, waited etc to be told there was no one working at the weekend who can do casts. What? At an a and e in a city of this size no one can put on a cast? Ridiculous, especially after I'd already rung up and been told they could.
