People have limited time, money and brainpower. If you’ve been working 8 hours and you have to go home and do housework, put the kids to bed, walk the dogs etc., you’re going to choose the easiest option for dinner even if you disagree with the prices or the company. As long as it’s not taking the piss, it’s not worth the hassle. This is the squeeze that “the sociopaths in charge” have put most of the working class in - don’t blame individuals caught in shitty circumstances for being stupid when this setup was done on purpose
