haawwwww! serving daal roti to the guests?
What ever happened to the three/four course meal with 3 to 4 side sweet dishes? and ufffffffff how can you forget chai and samosas?
you see in the west it has become a custom to serve like a “buffet” style - even breakfast - so if the guest are not sure if they will come or not then you can’t prepare anything - cause you have FULL TIME job and all that crap.
Besides grocery shopping itself will take away so many hours. 
I would love to serve daal roti and get it over with!!!
