I've said the same thing many times.
How about the soccer moms with their passel of screaming kids, standing in line for ten minutes and when they get up to the register, only THEN do they ask their kids, “what do you want to eat?” They read the entire f-ing menu to each one and every freaking thing has to be questioned - is there gluten in that, do you have diet root beer, can you make him a hot burger.
I have almost spontaneously combusted. Seriously, they need to go to the back of the line.
