I didn't know they have this feature in the receipt when every time you ask for paying the bill. I was having dinner with my wife at one of the famous steak house at batu satu there. If you look down the bottom of the receipt as you can see "Sales Per PAX" which mean that average that table each person how much they eat. So you not need to sakit kepala to think how much everyone eat already. Of coz this is only can for those people who don't kira-kira one lah, If like he eat $30 and me eat $25.00 why I have to pay for him them this calculation tak takai already!!!
