✔ 最佳答案
NEVER EVER APOLOGIZE. That is equal to admitting fault. Trust me, I'm a manager at a restaurant and if you apologize, they will use that against you in court. The best thing to do is contact your manager or owner. If it's something in the food you gave them, other people will get sick as well. If no one else reports illness, you almost definitely have nothing to worry about--logically, it had to be something else the person ate that day.
