First ring Philly burb. The McD's I normally frequent are inside Philly limits. Spanish speaking crews here win hands down for both efficiency and curtesy.
LOL. The McDonald's near where I work has two morning crews, one all Mexican, one all black.
The days the Mexicans are running the place, the facility and the employees are clean, the orders are correct and fast, and one gets the impression that the actually appreciate your business.
On the days the blacks are running it, the place is a mess. Fat sloppy women in filthy uniforms is the rule, and they will ALWAYS finish their personal (non work related) conversation before waiting on a customer. Never a "please", and you can forget about ever hearing a "thank you". Orders take forever to come out, and are often wrong.
It is actually so bad that when someone from work is thinking about going out to get biscuits for breakfast, they will ask the guy who stops there for coffee before work, "Is it black day, or Mexican day?"
If he says "Black day", we just wait until lunch.
