Standard mileage rate. Deducting these other stuff possible?
I am a rideshare driver using standard mileage rate for tax deduction. Can I deduct mileage going to restaurant's drive-thru ordering food "just for myself - no rider is in the car" while I am on the clock? Is my food in this case is tax deductable? How about going to a place to use its restroom - is the mileage considered deductable?
