When you order food and it is awful and you don't want to pay for it What do you do?

I pay for it......

First, you don't continue to eat it. Complain to the server and ask to see a manager.

This has happened to me a lot as I visit my sister in Thailand. Normally even from a street stall the food is gorgeous but sometimes in a restaurant the food is disgusting.

I learned from my sister her husband and their friends if your food is not good tell the waiter/waitress why and they will organise a replacement, if that is not good then simply refuse to pay and walk out.

In Thailand it works I have never tried it in UK.

I usually don't have to say anything, my bf has no problem sending the food back and telling them the issues. He usually gets it all comped and a free gift card in the process. Charm of a sociopath

You don't order food from them ever again.

You can always send it back. Maybe try something else.

Online reviews can really harm .... Though if you do bad work at times then you should expect others to do a bad job too at times ....

Notify the waiter/waitress and send it back, but don't be a jerk about it. They didn't cook your food.
