I worked at AutoZone 7 years ago, we had a scanner thing that'd just read the check numbers on the bottom and run it like a debit card without a pin.

I'd tell people to not fill out the check, cause it doesn't matter at all, it didn't read it, and I give the check right back anyway, it could even be used again if the dorks would stop filling them out for no reason.

Even after all my telling them before and while they filled them out, they'd be in such disbelief when I returned their check after 3 seconds. Some would even be angry for them wasting time filling it out when it didn't even matter. Like guy I told you multiple times, how could anyone get upset at me for that.
