Whether it’s a sit down restaurant or even fast food. Asking for this on the side, and to remove x, y, and z, extra this, or creating an order that is not even on the menu.
My line for what is excessive is shrinking too.
My annoyance with this type of ordering has pivoted me into the other extreme where I would rather order something else than even slightly custom order something.
There are probably exceptions. Some of you guys are just too picky though and should grow up and learn that onions or mushrooms are great.
The end.
