Khun Saen,
When I have a look at the daily sales of the rooftop, I really don't understand.
The service charge always showed negative before like :
Cheese platter 380 -38
And when there was a free cocktail, I could also understand.
But now, you have negative service charge and positive service charge (have a look at Ceasar Salad 260 2.60
At the rooftop bar, there's no take away, so there should be always service charge. But please revise the system so I can understand better.
What's wrong with the system??
Regards,
Hidenori
