While not ATL, I have yet to find someplace that accepted the 'meal vouchers'. Recent experience was a voucher with a QR code. Nobody knew what to do with it and systems weren't able to scan the code as payment. Places also would not manually key in the CC number - they wanted an actual card to swipe or tap.

I find the vouchers 100% useless at this point, and I ended up having to save receipts and turn them in for reimbursement later.
