People don't have to eat anything they don't like. They can sue if there is a law against it; if there is no law they can lobby their legislature to pass laws against it. The problem is that petty injustices like this are hard to fight because finding other plaintiffs is hard. The only thing connecting them is the defendant, who is not interested in helping them find each other. (In general, I believe that the sum of the damage of petty injustice is far greater than the major injustices that occasionally get some action on them, and that addressing these smaller injustices is a big juicy problem for society to solve.)
