- 5-10 minutes at beginning and end of shift to count cash drawers in and out, and make deposit bags, per employee
- 10-15 seconds per cash transaction to count payment and make change
- 60 minutes to prepare daily cash bank deposit and restock change (once, done by a supervisor)
- Employee theft from cash drawers, while not a common issue, did happen probably at least once a year
Now, I couldn't say if that all adds up to an extra 1-2% overhead, but I think its disingenuous for people to suggest that merchant fees charged by credit cards have little to no benefit to retailers. I think we'll see way more businesses go to electronic payments only within 10 years or so.
In recent months I have seen the latter system (human cashier + cash-handling machine) in a Madrid airport restaurant and a Romanian hypermarket.

I think people have claimed that when the experiment was done by capping fees, things don't get cheaper, so your viewpoint may not be accurate.
