I want to ask that both my wife and I's meals be remade at a restaurant
Why do you want to bother the restaurant like that?
They served us food for 3 not 2.
I get that you want your food to be perfect, but you shouldn't bother the chefs like this for a petty reason. Your food is a good enough portion, just save the leftovers and don't ruin the chefs' days.
Screw you and I'm going to request for a manager to remake my food.
You have already received your food and an extra plate. You can just enjoy it then have some to enjoy tomorrow for a snack or something. You shouldn't cause a big scene and yell at people.
