My POS system froze on a $1,200 order at my shop on Woodward, here is how I stopped panicking
Last Saturday during the lunch rush my card reader died mid-transaction and instead of losing the sale I wrote the guy's number on a napkin and rang him up once it rebooted, so what's your backup plan when the tech quits on you?
The napkin phone number backup is honestly genius, way classier than my move of just standing there staring at a frozen screen like it owes me money. My real backup is a $20 card reader from the drugstore that I keep in the drawer, because tech always quits at the worst time. Good on you for not letting the lunch rush eat your sale.
