Used it at SF Giants clubhouse yesterday. Sat at the bar and mentioned that I was using PP. Guy with the scanner came over and scanned my card and gave the ‘receipt’ to the bartender. I wasn’t hungry so I ordered a $26 half bottle of Moët.

When the bill came, PP didn’t cover taxes and I was responsible for $0.84 + tip.

Its not exactly a smooth operation yet but I suspect it will get better. Charge was coded as “employee discount” on the receipt.
