I have a very busy PO, however the manager who knows I come in nearly every day, just lets me leave them on one of his unmanned counters & then scans them later when he has the time.  Never had any issues with the scanning.  Maybe you could have a word with the manager & see if that's possible for you.  In the tradition of full disclosure I must admit that I'm a wiz-bang cake maker & have been known to take in said goodies  for their morning tea now & then   - fair exchange!! I say.

Good luck & brush up on your cooking skills!!
