McDonalds: Why is it almost impossible to get a hot meal at McDonalds or a burger with the cheese actually melted as opposed to barely warm burgers and cold unmelted cheese?

Why are they so cheap with the 1/4 piece of cold cheese and bun almost never properly placed on their filet of fish?

And, why do they not have an email address where consumers can make their complaints known or is it because they really don’t give a damn what customers think?

Why do none of their employess in any of their locations I have been in ever wear gloves?
