I am thinking of sending back a meal at a restaurant and blow the situation totally out of proportion.
Are you going to send it back to the restaurant because you're not happy with the food?
Yes, I will do that because I deserve respect
It can be disappointing when you don't like the food you ordered, but there's no reason to make a scene about it. Just politely ask the server for something else, and they'll probably be happy to accommodate you. Blowing the situation out of proportion just makes the server feel bad, and will ruin their day for no reason.
Nah, I'm going to take this to a manager and make a big deal about it.
Creating drama like this will look equally as bad for yourself. Imagine if this blows up on social media and everyone recognizes you as the "Karen" that made such a fuss over nothing. If you want to remain discrete, do it politely and get over it quickly.
