@cmconseils When we did our relaunch, my location had qr codes on stickers in the bowling area & concessions lobby. They worked fine for the kitchen, but the bar had no clue where the drinks were going or who ordered them, and if they wanted popcorn or cokes from the concessions, that never printed out anywhere. So we would have to get them to open up their order so we could see what they'd pay for, write it down, and go get it.
Our system was terrible; we hated it because we knew most were using it just to avoid tipping the bartender or us servers (and some folks don't tip anyway, so it was like "whatever"). The owners kept saying they were fixing them for months, but when the kids just started peeling the QR stickers off and playing with them, managers didn't replace them anymore & they all disappeared in a couple weeks. Nobody complained, not even the customers because they were tired of it taking twice as long to get their orders.
