I don't see why we should just roll over and accept the crap that they keep putting us through, especially since the government is here to serve us, the citizens. However, I'd suggest that the appropriate target for your frustration should be federal politicians, CATSA bureaucrats and GARDA management (in that order).

Ignore the fry chefs staffing the line, not because "it's easier" but but because it won't make any difference (unless you are planning to challenge the status quo via a lawsuit, but doubt that's your intention).
