How insecure are you that you need "customer service" and people tapdancing for you at a fukking fast food joint? You guys really fulfilled at a person pretending they care about your day in the slightest?
Take your shyt and move on.
If theres any insecurity involved in patroning a McDonalds, rest assured that its coming from the employee.

As far as general etiquette, theres more disrespectful workers than there are disrespectful customers. But this is a personal observation that will differ person to person. Theres undesirables on both sides for sure. Some customers do too much but make no mistake about it, some employees do entirely too much as well. The encounters have less to do with than being a patron vs employee and more to do with individuals themselves.
In fact, I've noticed that people who work in the service industry, fast food and retail, tend to be same muthafukkas going elsewhere and being difficult as shyt. The irony is palpable.
