I reckon you get what you deserve if you eat at fast food places.
are you saying if someone orders a fresh salad sandwich on a wholemeal bread, from Subway, they deserve bad customer service because Subway (just using it as an example here), is also a fast food place.?
following similar logic, anyone buying from shops that sell cheap goods, should also receive bad service...
flying with a cheap airline... again, should one expect bad service... (both from the flight staff and the pilot)

in conclusion, if you get paid less, does that mean you should be rude and do a sh1t job... tell you what, even many security guards in shopping centers are not really paid much... what happens if you get attacked, and the "low paid" security guard walks by...
i.e. how do you draw a line where you should start expecting good customer service?
there is a fast food joint in melb - called Don Don... a tiny small Japanese take away... cheap... they always smile when you take order, and you get served the food before you finish putting the wallet in your pocket (fresh/warm)... every single time.... no exceptions...
