Sean. This is 1 time. You're actually wrong. The couple Walmart said I frequent they're not in the best areas while I'm working and they have already turned off, all their stuff check self-checkouts and have employed a lot more people back to the regular checkout because maybe their losses are just too great versus everybody stealing versus just employing a few more people. But certain areas. Yeah, they have it in limited self-checkout but in the sketchy areas, they definitely are. People are probably stealing a whole bunch and Walmart has never had tap to pay on. It's always insert your card. They've never implemented where it's just Wireless or tap to pay.
