How do you handle situation like if customer complaints about food is not hot?

the old stand by, is the custmore is always right. WIth care and concearn, and ask what they would like as remedy, and if they EAT it and want it for free that is a scam, and offer to cook ANOTHER dish, (replacment) and try to get it too them quickly as it may have infact sat under the lights too long, or on the chefs shelf too long, ------------------------------------------------------------------------- I agree with the above, but there is another dimension that needs to be addressed too - If the customer was correct in the complaint then, as well as looking after that customer as described above, you also need to fix the system or you may lose all your customers. This is best done by keeping an internal record (i.e. what the complaint was about) of the complaints made by customers to see if there is a pattern. The complaints list needs to be reviewed regularly to see if things need fixing.
