Whoever it was that got your "BAD SERVICE" note is working a tough job made much worse by the exploitative remuneration system. They're having a hard day because every day is hard in a job like that -- and then you come along, all bent out of shape because you had to wait a whole 20 minutes and do a simple task for yourself. I'm not claiming that they're morally right to do so, but like it or not they *are* going to dunk the cook's nasty sweaty nuts in your diet Coke before they bring it to you, if you ever go back there. Being *right* might give you great satisfaction but it won't take the taste of hairy man-bits out of your mouth.
