Pay offered to frontline employees and thus the type of person hired into those jobs from the Atlanta metro area population base. The same folks are working in the ATL shops and dining establishments and kiosks, etc. But the traveling public accepts poor/rude service in an airport McDonald’s whereas they don’t from an airline agent, even though those individuals may well be making comparable salaries. Right or wrong, who knows, and Delta causes the raised expectations by telling customers we are “at the forefront of everything they do,” whereas McDonald’s implies nothing and basically just says we’ll get you some food in a short period of time - don’t go looking or asking for much more.
