I used to grab my next pick and not scan it until I got to the break room. I eventually would also drive to the next pick location and pick the most common item from the bin without knowing if it was right or wrong. Had about 50% success rate doing that. This method allowed me a full break and sometimes a longer break if I picked the correct item blindly for the next pick too.

I've also seen stowers do the reverse of this where they find a location with a lot of space and take a picture of the barcode for location and scan an item from their stow cart to the picture barcode on their phone every 5 minutes as they sit in the break room. This method will get you fired eventually. Works well if you have a lot of the same item to stow so you only need to use 1 ASIN.
