Went for lunch today ordered 2 quarter pounder meals for me and my coworker only to find our burgers were undercooked and the middle of the meat was still bright pink! Went back for a refund only to be asked if we wanted the burgers well done instead!! I Couldn't believe it! Your supposed to serve burgers well done! We dont want to contract E-coli!!! Absolutely ridiculous!!
