First of all there might be some problem with management about eating at workstation.
Secondly workplace must have microwave to heat it up
Third would be delivery time how can u deliver to 2 different place at the same time? regardless of morning or afternoon.

There are already those meal in box for microwave heating out there. cost a bit more expensive but with a lot of variety. doesnt sell well because of the problems above. (in office)

I would recommend u take canteen instead. So far the KL companies that I worked with have those canteen at underground car park. then u can choose to deliver or have walk in customer as well.

great menu there
wish you all the best
