Highway Patrol Says Pizza Can Trigger Their Breathaliser?

I work as a delivery driver for a certain pizza company. The other day while I was delivering I was pulled over for a breath test, cop says that he used to work for the same company and that I should get out of my car to do the test because supposedly the pizzas can set off the device.

I didn’t think much of it in the moment, the whole ordeal took less than a minute, but looking back I’m thinking that buddy just made that shit up so that he could see how I was on my feet.

Idk, what do you guys reckon
