Sometimes I buy the bread lol. The bread just gets made into other things if nobody buys it. Sliced after the first day, made into croutons the day after or a number of other bread goodness like garlic bread or used to make those pre-packed subs, etc. Or it's just tossed cause bread is cheap and making at the scale they make it makes it even cheaper.
By the way, if you have even a passing interest I recommend baking your own bread, unless you want sourdough and you don't want to spend that effort cause sourdough is next level effort. But a basic white bread is extremely easy and tastes so good fresh and lasts for soooo much longer than the store made breads.
