Have all the ACO accept cash ??
Sure. Why not? When CVS first deployed them years ago, they all accepted cash. I suspect they all can still be made to accept cash, in many cases it is obvious that the bill and coin slots are still there but covered up.
Not asking for the moon here. Really, asking for the level of service offered when the machines were first introduced. We know it is possible, because it was done before. The technology clearly exists (because there are still machines that accept cash), the infrastructure exists (it isn't like you need to rewire stores to support machines that accept cash, particularly since they are in the same spots that once supported cash-accepting self-checkout machines), and it has been shown that CVS could logistically support them (because CVS once had all of their self-checkout machines accept cash).
It isn't a question of CVS being unable to. It is entirely a question of CVS management's willingness to do so.
Who the heck uses cash anymore ?
Pretending to be shocked that people still use cash stopped being funny years ago. It honestly makes you look like an id--t.
The bottom line is CVS leadership thinks it can take customers for granted. And then they whine about it when customers say they have had enough, just look at the comments in this thread.
