McDonalds
Staff ignored me at Kenmore Square location

First, nice try with the math question. Perhaps you should give it a try with your new employees. That should weed down the herd.
This morning I apparently bothered/interrupted your staff. This is why I'll never darken your lazy, slow & rude door again.
I will be sure my friends and neighbors will do the same.
The DD next door is a better choice.
