I applied for it, didn't get it. I've applied for about a dozen jobs a week, and never get any of them or hardly hear back from them. Usually when I do, it is to tell me that I am not skilled enough, or am not qualified enough, or some other reason they do not want to hire me.
I cannot even get those fast food jobs, but I keep on trying.
Besides the food bills, there is the electric bill, other utilities, my medical bills (I pay between $300USD and $500USD for perscription medicine a month and owe the hospitals a whole sh*tload of money), my credit card bills (only way I can survive is charge it and pay it off later), and the gas money for my car. Rent, as you said, wouldn't be higher, but the other bills would be higher. I could always sleep on the couch if there is no room in the bed.
I hate fast food jobs, I had two of them while in college. They work you too hard for minimum wage and I always get screwed out of the job after a while because of politics and favortism and because I don't smooze around with the managers.
