Fun post--I love a brain teaser! The Mechanic killed Colonel Tire, with a lug wrench, in Garage #1...
Rims are not unidirectional, many tires are. When you bought the car, you had 4 tires spinning the correct way. The mechanic at Garage #1 rotated your tires by swapping the corners--front right with left rear, front left with right rear. This is typical for nondirectional tires, but it reverses the direction of the spin, so then you had 4 tires spinning the wrong way. With directional tires the correct swap is to move the front tires to the rear, but keep the tires on the original side of the car.
The line about only checking directionality with a rim change is a red herring
