i'm thinking of putting up a step-by-step tutorial in the window:
- remove the ink pad from the drive-thru drawer (this is an important step as simply pressing your finger to the check without ink does not work)
- the top part is a lid. open it (the lid does not have ink on it, no matter how hard you press on it)
- press firmly on the ink pad until your finger is covered in ink
- now press your finger on the ckeck (yes, a finger print should be visible after this step... it's not clear ink. if you can't see the print, you need more ink)
who would have thought it's such a difficult process?!
