When a customer believes he or she has ingested contaminated food in your establishment, you should o immediately contact the restaurant's legal department or attorney
Obe careful not to imply that the restaurant is at fault
O be prepared to believe the customer and take immediate action to correct the problem
politely inquire about other possible causes for the customer's symptoms besides food contamination

It is not I repeat not the last one-

Politely inquire about other causes for the customer’s symptoms besides food contamination

My next guess would be the first one-

Immediately contact the restaurants legal department or attorney.
