When people get sick after eating at a restaurant, they often contact the restaurant to complain or report the sickness. The restaurant may apologize and offer a refund or a free meal. However, you should be careful if the business asks you to sign anything. A restaurant may offer a refund, gift certificate, or replacement meal as a sign of good customer service for a bad meal. The business might also try and get you to sign a waiver as a condition of accepting the payment or credit. The waiver may be a legal waiver of your right to sue. This could mean that you are agreeing not to file a lawsuit against the company in exchange for some compensation, even if it is as little as a free meal. Before you sign away your legal rights, consult a lawyer about your rights and potential damages.
