How hard can it be? It's not like calculating the velocity of an asteroid hurtling through space towards earth and we need to know how long we have to live, it's putting six, no wait, five, duh, no onions, together. Thing that really sets this one particular incident aside from others is that the guy that took my order told the guy building the burger " no onions" four times that I heard, WHILE THE BURGER WAS BEING PUT TOGETHER. Not like there was a big rush on, only two burgers were ordered. Both were on my order. Minimum I.Q. requirement for the job, 12.
